Remove some wasm/emscripten ignores
I'm planning on landing a few PRs like this that remove ignores that aren't required. This just covers mir-opt and codegen tests.
Move a local to the `#if` block where it is used
For other cases (LLVM < 17), this was complaining under `-Wall`:
```
warning: llvm-wrapper/PassWrapper.cpp: In function ‘void LLVMRustPrintTargetCPUs(LLVMTargetMachineRef, const char*)’:
warning: llvm-wrapper/PassWrapper.cpp:311:26: warning: unused variable ‘MCInfo’ [-Wunused-variable]

This reverts commit 4410868798, reversing
changes made to 249595b752.
This causes linker failures with the binutils version used by
cross (#115239), as well as miscompilations when using the mold
linker.
compile rust-anaylzer with `x check` if it's enabled
By default, `x check` doesn't compile the rust-analyzer. But when it's enabled in the config's tools section, there's no reason not to do it. This change allows `x check` to compile rust-analyzer if it's enabled in config's tools section.
Helps to #115031
Correct and expand documentation of `handle_alloc_error` and `set_alloc_error_hook`.
The primary goal of this change is to remove the false claim that `handle_alloc_error` always aborts; instead, code should be prepared for `handle_alloc_error` to possibly unwind, and be sound under that condition.
I saw other opportunities for improvement, so I have added all the following information:
* `handle_alloc_error` may panic instead of aborting. (Fixes#114898)
* What happens if a hook returns rather than diverging.
* A hook may panic. (This was already demonstrated in an example, but not stated in prose.)
* A hook must be sound to call — it cannot assume that it is only called by the runtime, since its function pointer can be retrieved by safe code.
I've checked these statements against the source code of `alloc` and `std`, but there may be nuances I haven't caught, so a careful review is welcome.
coverage: Tidy up `run-coverage` tests in several small ways
Prior to #114875 (anonymized line numbers), these tests were very sensitive to lines being added/removed, since doing so would change the line numbers in every subsequent line of output. Therefore they ended up with a few small style issues that weren't worth the hassle of fixing.
Now that we can freely rearrange lines without needing to re-bless the entire output, we can tidy up the tests in various trivial ways.
Go into more detail about panicking in drop.
This patch was sitting around in my drafts. I don't recall the motivation, but I think it was someone expressing confusion over “will likely abort” (since, in fact, a panicking drop _not_ caused by dropping while panicking will predictably _not_ abort).
I hope that the new text will leave people well-informed about why not to panic and when it is reasonable to panic.
As experimentation in 115242 has shown looks better than `coldcc`.
And *don't* use a different convention for cold on Windows, because that actually ends up making things worse.

Fix#105306.
Remove lub_empty from lexical region resolve
As of my understanding this method made sense when we had `ReEmpty`.
Removed `lub_empty` and made the calling site code equivalent.

C11 `aligned_alloc` requires that the size be a multiple of the
alignment. This is enforced in the wasi-libc emmalloc implementation,
which always returns NULL if the size is not a multiple.
(The default `MALLOC_IMPL=dlmalloc` does not currently check this.)
Fix waiting on a query that panicked
This fixes waiting on a query that panicked. The code now looks for `QueryResult::Poisoned` in the query state in addition to the query cache. This fixes https://github.com/rust-lang/rust/issues/111528.

Make `rustc_on_unimplemented` std-agnostic for `alloc::rc`
See https://github.com/rust-lang/rust/issues/112923
Just a few lines related to `alloc:rc` for `Send` and `Sync`.
That seems to be all of the `... = "std::..."` issues found, but there a few notes with `std::` inside them still.

It's unclear what makes this not work sometimes, since it often *does* work, so for now just disable the unusual cases. A future PR can consider doing something smarter, but this is an easy and safe tweak that we can do to resolve the regressions for now.
