When using the `--test` or `--all-targets` flag, the exit lint should not fail on the main function.

Disable download-rustc for library profile
The feature currently completely breaks `x test` (rust-lang/rust#142505), core functionality of working on the standard library. Therefore it should be disabled by default until that problem is fixed. Having to wait a bit longer for a check build is nothing compared to completely mysterious build errors when testing.

compiler: Deduplicate `must_emit_unwind_tables()` comments
There is one comment at a call site and one comment in the function definition that are mostly saying the same thing. Fold the call site comment into the function definition comment to reduce duplication.
There are actually some inaccuracies in the comments but let's deduplicate before we address the inaccuracies.

std: fix typo in `std::path`
I noticed that most of the document used `'` instead of `’`, so I adjusted it.

Dont resolve instance of root in `mir_callgraph_cyclic`
`Instance::try_resolve` on a default trait body method will always fail, since it's still possible to further substitute. This leads to a cycle, since in `tests/mir-opt/inline_default_trait_body.rs`, both `Trait::a` and `Trait::b` need to consider the other to be cyclical, but since we couldn't resolve a body, we'd just consider *nothing* to be cyclical.
The root instance we care about when computing `mir_callgraph_cyclic` is trivial to compute (it's just `InstanceKind::Item`), so just replace it with a call to `Instance::new_raw`.

interpret: rename StackPopCleanup
The name `StackPopCleanup` stopped making sense a long time ago IMO -- in the common case, it has nothing to do with "cleanup", and everything with where the program should jump next. If we didn't have unwinding this would be just the return block, but given that we do have unwinding I figured maybe "continuation" would be a good name. This comes up in [continuation-passing style](https://en.wikipedia.org/wiki/Continuation-passing_style) and refers to where the program will *continue* when a function is done. So from a PL perspective it is the most fitting term I think -- but it may be too jargony.
r? `@oli-obk` what do you think?

Move `stable_mir` back to its own crate
We've finished the refactoring, so it's time to move `stable_mir` back to its own crate.
This PR leaves an empty `rustc_internal` module with a `#[deprecated]` attribute in `rustc_smir` to let users know we just moved it to `stable_mir`.

Fix short linker error output
This PR does 2 things:
- It removes the braces when there's a single element. This is required since brace expansion (at least in bash and zsh) only triggers if there's at least 2 elements.
- It removes the extra `.rlib` suffixes of the elements. See https://github.com/rust-lang/rust/pull/135707#discussion_r2185212393 for context.
Running `cargo +stage1 build` on the following program:
```rust
unsafe extern "C" {
fn foo() -> libc::c_int;
}
fn main() {
let x = unsafe { foo() } as u32;
// println!("{}", data_encoding::BASE64.encode(&x.to_le_bytes()));
}
```
Gives the following diff before and after the PR:
```diff
-/tmp/foo/target/debug/deps/{liblibc-faf416f178830595.rlib}.rlib
+/tmp/foo/target/debug/deps/liblibc-faf416f178830595.rlib
```
Running on the same program with the additional dependency, we get the following diff:
```diff
-/tmp/foo/target/debug/deps/{liblibc-faf416f178830595.rlib,libdata_encoding-84bb5aadfa9e8839.rlib}.rlib
+/tmp/foo/target/debug/deps/{liblibc-faf416f178830595,libdata_encoding-84bb5aadfa9e8839}.rlib

Make tests/ui/abi/debug.rs cross-compile

Get rid of build-powerpc64le-toolchain.sh
The dist-powerpc64le-linux-musl runner never actually used the toolchain that the script produced, it instead used the one from crosstool-ng.
The dist-powerpc64le-linux-gnu runner did use it, from what I can tell mainly to get a glibc 2.17 version with ppc64le support backported. Since crosstool-ng has the necessary patches, we can just use crosstool-ng to get an appropriate toolchain. While at it, use kernel 3.10 headers since that's the version documented in platform support for this target.

When a trait bound fails due to the Self type parameter, adjust_fulfillment_errors
now correctly points to the corresponding function argument instead of incorrectly
pointing to other arguments.

Enforce in bootstrap that check must have stage at least 1
This PR is another step towards https://rust-lang.zulipchat.com/#narrow/channel/326414-t-infra.2Fbootstrap/topic/Proposal.20to.20cleanup.20stages.20and.20steps.20after.20the.20redesign/with/523586917, this time dealing with `x check`.
It enforces the invariant that:
- We check std stage N with rustc stage N
- We check everything else stage N with rustc stage N - 1
It creates a single function that prepares a proper build compiler for checking something, and also adds snapshot tests for various common check steps. Some obsolete code was also removed.
The default check stage also becomes 1, for all profiles. I tested manually that `x check std` with `download-ci-rustc` still works and doesn't build rustc locally.
