improve `filesearch::get_or_default_sysroot`
`fn get_or_default_sysroot` is now improved and used in `miri` and `clippy`, and tests are still passing as they should. So we no longer need to implement custom workarounds/hacks to find sysroot in tools like miri/clippy.
Resolves https://github.com/rust-lang/rust/issues/98832
re-opened from #103581

Make mir opt unused file check blessable
Makes it slightly nicer to work with.
Can't write automated test but tested locally via
```
$ touch src/test/mir-opt/random
$ x test tidy // shows failure
$ x test tidy --bless // file gone
```

Ensure that compile-flags arguments are the last in UI tests
Before this PR, compiletest would add `-L path/to/aux` at the end of the rustc flags, even after the custom ones set with the compile-flags header comment. This made it impossible to check how rustc would behave when a flag requiring an argument was passed without the argument, because the argument would become `-L`.
This PR fixes that by adding the `-L path/to/aux` before the arguments defined in compile-flags, at least for UI tests. Other test suites might either be fixed as well by this change, or still present the old behavior (`-L` is now always passed before, but other tests suites might add additional flags after the custom ones).

InitOnce: synchronize with completion when already complete
The completion of an InitOnce happens-before the threads waiting on it wake up. However, this is not the case for threads that call `InitOnceBeginInitialize` after the completion, leading to data races and outdated weak memory loads as observed in the CI for #2638. This PR fixes this.

This reverts commit 331aa4509315f670803b7e232486be84d84ea686.
This Cargo upgrade introduced a regression into dependency resolution,
so reverting the upgrade until we can fix that.

Ban dashes in miropt test file names
Dashes in miropt test file names are annoying - specifically, they cause the test files to not be sorted next to their outputs, which makes it very difficult to tell what goes with what. This PR changes all files to use underscores and adds a blessable tidy check that enforces this.
r? `@jyn514`
This PR is obviously going to bitrot very quickly. Because of this, I'm going to wait at least 48 hours and until review comes back to allow people from `@rust-lang/wg-mir-opt` or elsewhere to lodge complaints if there are any. If not, I'll rebase the branch on Friday afternoon PST and ask that it be `r+`'d with `p=1` at that time.

Update tinystr
Tinystr has changed a ton since the old version and is much less unsafe, updated some of the dependencies that use it.

Detect unused files in `src/test/mir-opt` and error on them in tidy.
Closes #97564 .
Determining which files are generated by a given mir opt test is somewhat difficult. Because of this, we extract the logic for doing it out into a common crate that both compiletest and tidy can depend on. This avoids making compiletest a dependency of tidy which would negatively impact compile times for tidy.
Testing for this is that it catches 5 files that violated this lint (and removes them).

compiletest: set the dylib path when gathering target cfg
If the compiler is built with `rpath = false`, then it won't find its
own libraries unless the library search path is set. We already do that
while running the actual compiletests, but #100260 added another rustc
command for getting the target cfg.
Check compiletest suite=codegen mode=codegen (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu)
thread 'main' panicked at 'error: failed to get cfg info from "[...]/build/x86_64-unknown-linux-gnu/stage1/bin/rustc"
--- stdout
--- stderr
[...]/build/x86_64-unknown-linux-gnu/stage1/bin/rustc: error while loading shared libraries: librustc_driver-a2a76dc626cd02d2.so: cannot open shared object file: No such file or directory
', src/tools/compiletest/src/common.rs:476:13
Now the library path is set here as well, so it works without rpath.

Track where diagnostics were created.
This implements the `-Ztrack-diagnostics` flag, which uses `#[track_caller]` to track where diagnostics are created. It is meant as a debugging tool much like `-Ztreat-err-as-bug`.
For example, the following code...
```rust
struct A;
struct B;
fn main(){
let _: A = B;
}
```
...now emits the following error message:
```
error[E0308]: mismatched types
--> src\main.rs:5:16
|
5 | let _: A = B;
| - ^ expected struct `A`, found struct `B`
| |
| expected due to this
-Ztrack-diagnostics: created at compiler\rustc_infer\src\infer\error_reporting\mod.rs:2275:31

Accept `TyCtxt` instead of `TyCtxtAt` in `Ty::is_*` functions
Functions in answer:
- `Ty::is_freeze`
- `Ty::is_sized`
- `Ty::is_unpin`
- `Ty::is_copy_modulo_regions`
This allows to remove a lot of useless `.at(DUMMY_SP)`, making the code a bit nicer :3

Rename some `OwnerId` fields.
`@spastorino` noticed some silly expressions like `item_id.def_id.def_id`.
This commit renames several `def_id: OwnerId` fields as `owner_id`, so those expressions become `item_id.owner_id.def_id`.
`item_id.owner_id.local_def_id` would be even clearer, but the use of `def_id` for values of type `LocalDefId` is *very* widespread, so I left that alone.
