1c6d867d78 wasi: round up the size for aligned_alloc
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.

Stop emitting non-power-of-two vectors in (non-portable-SIMD) codegen

Fixes #115212

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.

8d91e71e9a Various trivial formatting fixes in run-coverage tests
These changes were made by manually running `rustfmt` on all of the test files,
and then manually undoing all cases where the original formatting appeared to
have been deliberate.

  `rustfmt +nightly --config-path=/dev/null --edition=2021 tests/run-coverage*/**/*.rs`

4da38c31d2 Tidy up some awkwardly-placed comments in tests
Prior to #114875, these tests were very sensitive to lines being added/removed,
so the migration to `run-coverage` in #112300 tried hard to avoid disturbing
the existing line numbers. That resulted in some awkward reshuffling when
certain comments/directives needed to be added or moved.

Now that we don't have to worry about preserving line numbers, we can rearrange
those comments into a more conventional layout.

72b721f48e Resolve all warnings in run-coverage tests
When one of these tests fails, any compiler warnings will be printed to the
console, which makes it harder to track down the actual reason for failure.

(The outstanding warnings were found by temporarily adding `-Dwarnings` to the
compiler arguments for `RunCoverage` in `src/tools/compiletest/src/runtest.rs`.)

9334ec9354 Auto merge of #115228 - saethlin:is-interrupted, r=thomcc
Add a new helper to avoid calling io::Error::kind

On `cfg(unix)`, `Error::kind` emits an enormous jump table that LLVM seems unable to optimize out. I don't really understand why, but see for yourself: https://godbolt.org/z/17hY496KG

This change lets us check for `ErrorKind::Interrupted` without going through a big match. I've checked the codegen locally, and it has the desired effect on the codegen for `BufReader::read_exact`.

Walk through full path in `point_at_path_if_possible`

We already had sufficient information to point at the `[u8]` in `Option::<[u8]>::None` (the `fallback_param_to_point_at` parameter), we just were neither using it nor walking through hir paths sufficiently to encounter it.

This should alleviate the need to add additional logic to extract params in a somewhat arbitrary manner of looking at the grandparent def path: https://github.com/rust-lang/rust/pull/115219#discussion_r1305946358

edefa8b105 Added option to set ProcThreadAttributes for Windows processes
This implements the ability to add arbitrary attributes to a command on Windows targets using a new `raw_attribute` method on the [`CommandExt`](https://doc.rust-lang.org/stable/std/os/windows/process/trait.CommandExt.html) trait. Setting these attributes provides extended configuration options for Windows processes.

After seeing https://rust-lang.zulipchat.com/#narrow/stream/136281-t-opsem/topic/Packed.20fields.20and.20in-place.20function.20argument.2Freturn.20passing, this may be UB, so should be disallowed.

This should not appear in normally-built MIR, which introduces temporary copies for packed projections.

thread caused non-unwinding panic. aborting.
```
If we also land https://github.com/rust-lang/rust/pull/115020, the 2nd backtrace disappears, hopefully making the "panic in a destructor during cleanup" easier to see.

Fixes https://github.com/rust-lang/rust/issues/114954.
