r=Mark-Simulacrum
Removed dependency on the field-offset crate, alternate approach
This is an alternate approach to reach the same goals as #136003. As it touches the core of the query system, this too probably should be evaluated for performance.

tests: Port `split-debuginfo` to rmake.rs
Part of #121876.
This PR supersedes #128754 and is co-authored with `@Oneirical.`
## Known limitations
- In general, like the `Makefile` version, this test in its present form is also somewhat funny because for the most part it merely checks for existence/absence of output artifacts but makes no attempt to actually check if the debuginfo is at all usable.
## Changes
This PR ports `tests/run-make/split-debuginfo` to rmake.rs. This is an **initial** port, and certainly could be cleaned up and/or enhanced.
The original Makefile version had several functional problems. I fixed some of them, but also left some existing issues as-is.
1. The linux/non-linux final branch had a conditional interpolation of `UNSTABLE_OPTIONS := -Zunstable-options`. However, one of the use sites was `-C $(UNSTABLE_OPTIONS) split-debuginfo`. This indicates to me that this run-make test is not run in CI under a non-linux + non-windows + non-darwin environment, because that would've failed as this would expand to `-C -Zunstable-options split-debuginfo`. I fixed this in the rmake.rs version, but I'm not sure if this distinction is worth keeping at all if it's not tested in CI.
2. There are several comments that were discovered to be wrong. I tried to fix them in the rmake.rs version as well.
3. The check for path remapping / lack of path remapping through
```make
objdump -Wi $(TMPDIR)/foo | grep DW_AT_GNU_dwo_name | (! grep $(TMPDIR)) || exit 1
```
is incorrect, because that looks at the single line of that contains `DW_AT_GNU_dwo_name`. This is unfortunately wrong because empirical evidence shows that with `objdump`[^objdump], the check actually needs to look at the attribute value of `DW_AT_comp_dir` on the previous line not `DW_AT_GNU_dwo_name`[^gnu-ext]. Example output of `objdump`:
```text
<10> DW_AT_comp_dir : (indirect string, offset: 0xafb48): /home/joe/repos/rust
<14> DW_AT_GNU_dwo_name: (indirect string, offset: 0x5d1b0): foo.foo.fc848df41df7a00d-cgu.0.rcgu.dwo
```
In the rmake.rs version I used a 2-line sliding window to check for `DW_AT_comp_dir` and `DW_AT_GNU_dwo_name`, but to look at `DW_AT_comp_dir` specifically.
4. I included a bunch of FIXMEs and ENHANCEMENTs I noticed regarding the test because I didn't want to fix them in this initial port[^enhancement].
5. The Makefile version didn't test *anything* on Windows (both windows-msvc and windows-gnu). I added some *very* basic and *very* sparse checks for windows-msvc, but I am not willing to spend the effort to expand test coverage to windows-gnu in this initial port.
6. This run-make test is way too big. But I didn't want to expend the effort of breaking this up in this initial port.
[^objdump]: the output format differs between `objdump` and `llvm-objdump`, but the same is true for `llvm-objdump` that this is looking at the wrong line.
[^gnu-ext]: AFAICT that is a GNU DWARF attribute extension, since it isn't mentioned in DWARFv5 spec
[^enhancement]: For instance, the previous path remapping check could in theory be precisely inspected by inspecting `.debug_info` section to look for attribute value of `DW_AT_comp_dir`. But that involves resolving the value of the indirect string, which means you have to: (1) look for offset into string offset table and (2) use *that* offset to find the string itself in the string table. The split part of "split-debuginfo" makes this murky for me, so I wasn't able to replace `llvm-objdump` textual output substring matches with more precise `object` + `gimli` inspections.
## Review advice
- I'm sorry for how long the rmake.rs test ended up, but a lot of it is comments and just vertical space due to formatting. If there's any ways to make this test less long / convoluted, advice would be appreciated.
- This PR *intentionally* introduces several intermediate commits for the `Makefile`, mostly to illustrate the problems I discovered when looking at the original `Makefile` version. This is intended to highlight the existing problems in the `Makefile` version for the reviewer[^squash].
- There are several intentional non-functional commits:
1. Reindent the `Makefile` to make the platform conditional gating more obvious.
2. Collapse nested if-else branches into an else if construct, which is not supported by GNU Make 3.80.
3. Remove all redundant `-C debuginfo=2` when `-g` is already specified.
- This PR is best reviewed commit-by-commit.
[^squash]: I intend to squash these intermediate commits away after the reviewer concludes that the current form of the rmake.rs test is acceptable for merge. Before then, I'll keep them to help with review.

Extract `core::ffi` primitives to a separate (internal) module
### Introduce library/core/src/ffi/primitives.rs
The regex preprocessing for PR #133944 would be more robust if the relevant types from core/src/ffi/mod.rs were first moved to library/core/src/ffi/primitives.rs, then there isn't a need to deal with traits / c_str / va_list / whatever might wind up in that module in the future

Ignore NLL boring locals in polonius diagnostics
Another easy one ``@jackh726`` (the diff is inflated by blessed test expectations don't worry :)
NLLs don't compute liveness for boring locals, and therefore cannot find them in causes explaining borrows. In polonius, we don't have this liveness optimization (we may be able to do something partially similar in the future, e.g. for function parameters and the like), so we do encounter these in diagnostics even though we don't want to. This PR:
- restructures the polonius context into per-phase data, in spirit as you requested in an earlier review
- stores the locals NLLs would consider boring into the errors/diagnostics data
- ignores these if a boring local is found when trying to explain borrows
This PR fixes around 80 cases of diagnostics differences between `-Zpolonius=next` and NLLs. I've also added explicit revisions to a few polonius tests (both for the in-tree implementation as well as the datalog implementation -- even if we'll eventually remove them). I didn't do this for all the "dead" expectations that were removed from #136112 for that same reason, it's fine. I'll soon/eventually add explicit revisions where they're needed: there's only a handful of tests left to fix.

- Don't show environment variables. Seeing PATH is almost never useful, and it can be extremely long.
- For .rlibs in the sysroot, replace crate hashes with a `"-*"` string. This will expand to the full crate name when pasted into the shell.
- Move `.rlib` to outside the glob.
- Abbreviate the sysroot path to `<sysroot>` wherever it appears in the arguments.
This also adds an example of the linker output as a run-make test. Currently it only runs on x86_64-unknown-linux-gnu, because each platform has its own linker arguments. So that it's stable across machines, pass BUILD_ROOT as an argument through compiletest through to run-make tests.
- Only use linker-flavor=gnu-cc if we're actually going to compare the output. It doesn't exist on MacOS.

Implement `needs-subprocess` directive, and cleanup a bunch of tests to use `needs-{subprocess,threads}`
### Summary
Closes #128295.
- Implements `//@ needs-subprocess` directive in compiletest as requested in #128295. However, compiletest is a host tool, so we can't just try to spawn process because that spawns the process on *host*, not the *target*, under cross-compilation scenarios.
- The short-term solution is to add *Yet Another* list of allow-list targets.
- The long-term solution is to first check if a `$target` supports std, then try to run a binary to do run-time capability detection *on the target*. But that is tricky because you have to build-and-run a binary *for the target*.
- This PR picks the short-term solution, because the long-term solution is highly non-trivial, and it's already an improvement over individual `ignore-*`s all over the place.
- Opened an issue about the long-term solution in #135928.
- Documents `//@ needs-subprocess` in rustc-dev-guide.
- Replace `ignore-{wasm,wasm32,emscripten,sgx}` with `needs-{subprocess,threads}` where suitable in tests.
- Some drive-by test changes as I was trying to figure out if I could use `needs-{subprocess,threads}` and found some bits needlessly distracting.
Count of tests that use `ignore-{wasm,wasm32,emscripten,sgx}` before and after this PR:

### Review advice
- Best reviewed commit-by-commit.
- Non-trivial test changes (not mechanically simple replacements) are split into individual commits to help with review. Their individual commit messages give some basic description of the changes.
- I *could* split some test changes out into another PR, but I found that I needed to change some tests to `needs-threads`, some to `needs-subprocess`, and some needed to use *both*, so they might conflict and become very annoying.

r=compiler-errors
For E0223, suggest associated functions that are similar to the path, even if the base type has multiple inherent impl blocks.
Currently, the "help: there is an associated function with a similar name `from_utf8`" suggestion for `String::from::utf8` is only given if `String` has exactly one inherent `impl` item. This PR makes the suggestion be emitted even if the base type has multiple inherent `impl` items.
Example:
```rust
struct Foo;
impl Foo {
fn bar_baz() {}
}
impl Foo {} // load-bearing
fn main() {
Foo::bar::baz;
}
```
Nightly/stable output:
```rust
error[E0223]: ambiguous associated type
--> f.rs:7:5
|
7 | Foo::bar::baz;
| ^^^^^^^^
|
help: if there were a trait named `Example` with associated type `bar` implemented for `Foo`, you could use the fully-qualified path
|
7 | <Foo as Example>::bar::baz;
| ~~~~~~~~~~~~~~~~~~~~~
error: aborting due to 1 previous error
For more information about this error, try `rustc --explain E0223`.
```
Output with this PR, or without the load-bearing empty impl on nightly/stable:
```rust
error[E0223]: ambiguous associated type
--> f.rs:7:5
|
7 | Foo::bar::baz;
| ^^^^^^^^
|
help: there is an associated function with a similar name: `bar_baz`
|
7 | Foo::bar_baz;
| ~~~~~~~
error: aborting due to 1 previous error
For more information about this error, try `rustc --explain E0223`.
```
Ideally, this suggestion would also work for non-ADT types like ~~`str::char::indices`~~ (edit: latest commit makes this work with primitives) or `<dyn Any>::downcast::mut_unchecked`, but that seemed to be a harder change.

This PR ports `tests/run-make/jobserver-error` to rmake.rs, and is basically #128789 slightly adjusted.
The complexity involved here is mostly how to get `/dev/null/` piping to fd 3 working with std `Command`, whereas with a shell this is much easier (as is evident with the `Makefile` version).
Supersedes #128789.

remove support for the (unstable) #[start] attribute
As explained by `@Noratrieb:`
`#[start]` should be deleted. It's nothing but an accidentally leaked implementation detail that's a not very useful mix between "portable" entrypoint logic and bad abstraction.
I think the way the stable user-facing entrypoint should work (and works today on stable) is pretty simple:
- `std`-using cross-platform programs should use `fn main()`. the compiler, together with `std`, will then ensure that code ends up at `main` (by having a platform-specific entrypoint that gets directed through `lang_start` in `std` to `main` - but that's just an implementation detail)
- `no_std` platform-specific programs should use `#![no_main]` and define their own platform-specific entrypoint symbol with `#[no_mangle]`, like `main`, `_start`, `WinMain` or `my_embedded_platform_wants_to_start_here`. most of them only support a single platform anyways, and need cfg for the different platform's ways of passing arguments or other things *anyways*
`#[start]` is in a super weird position of being neither of those two. It tries to pretend that it's cross-platform, but its signature is a total lie. Those arguments are just stubbed out to zero on ~~Windows~~ wasm, for example. It also only handles the platform-specific entrypoints for a few platforms that are supported by `std`, like Windows or Unix-likes. `my_embedded_platform_wants_to_start_here` can't use it, and neither could a libc-less Linux program.
So we have an attribute that only works in some cases anyways, that has a signature that's a total lie (and a signature that, as I might want to add, has changed recently, and that I definitely would not be comfortable giving *any* stability guarantees on), and where there's a pretty easy way to get things working without it in the first place.
Note that this feature has **not** been RFCed in the first place.
*This comment was posted [in May](https://github.com/rust-lang/rust/issues/29633#issuecomment-2088596042) and so far nobody spoke up in that issue with a usecase that would require keeping the attribute.*
