Remove alternate stack with sigaltstack before unmaping it.
Also reuse existing signal stack if already set, this is especially
useful when working with sanitizers that configure alternate stack
themselves.
This change depends on SS_DISABLE recently introduced in libc crate and updates
this git submodule accordingly.
This commit rebases our LLVM submodule on the most recent tip of the
`release_38` branch of LLVM. There's been a few fixes and this notably fixes the
assertion error in #31702.

this improves typeck performance by 5% (LLVM times are still huge).
Basically fixes#25916 (still O(n^2), but the example takes <1s to
compile).

This PR disallows non-inline modules without path annotations that are either in a block or in an inline module whose containing file is not a directory owner (fixes#29765).
This is a [breaking-change].

The issue was that the const evaluator was returning an error because
the feature flag const_indexing wasn't turned on. The error was then
reported as a bug.
Fixes#29914
This PR fixes two unrelated diagnostics bugs in resolve.
First, it reports privacy errors for an import only after the import resolution is determined, fixing #31402.
Second, it expands the per-module map from block ids to anonymous modules so that it also maps module declarations ids to modules, and it uses this map to in `with_scope` to fix#31644.

Some tests just add the extra errors, others I fix by doing some simple error recovery. I've tried to avoid doing too much in the hope of doing something more principled later.
In general error messages are getting worse at this stage, but I think in the long run they will get better.
Back in 9bc8e6d14 the linking of rlibs changed to using the `link_whole_rlib`
function. This change, however was only intended to affect dylibs, not
executables. For executables we don't actually want to link entire rlibs because
we want the linker to strip out as much as possible.
This commit adds a conditional to this logic to only link entire rlibs if we're
creating a dylib, and otherwise an executable just links an rlib as usual. A
test is included which will fail to link if this behavior is reverted.
The BSD grep for "basic regex" don't support \| as alternate operator (at least under OpenBSD).
Use multiple -e arguments for expressing alternative. I have checked it under Linux (Debian).

Ignores 82 rpass tests that use threads.
I took care to only ignore tests that call `thread::spawn`. Some tests, for example `issue-16597`, also do fail because of lack of threads support, but for other reasons.
With this PR, we're down to 49 failures.

I still need to add error code explanation test with this, but I can't figure out a way to generate the `.md` files in order to test example source codes.
Will fix#27328.
