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.
Make the dep. graph edges created by variance just mirror the constraint graph.
Note that this extends <https://github.com/rust-lang/rust/pull/31304>, so the first few commits are on a different topic.

The initial purpose is to workaround the LLVM bug
https://llvm.org/bugs/show_bug.cgi?id=26554 for OpenBSD.
By default, the `cpu` is defined to `generic`. But with a 64bit
processor, the optimization for `generic` will use invalid asm code as
NOP (the generated code for NOP isn't a NOP).
According to #20777, "x86-64" is the right thing to do for x86_64
builds.
Closes: #31363

Previously the docs suggested that '❤️' doesn't fit in a char because
it's 6 bytes. But that's misleading. 'a̚' also doesn't fit in a char,
even though it's only 3 bytes. The important thing is the number of code
points, not the number of bytes. Clarify the primitive char docs around
this.
The first time I read the docs for `insert()`, I thought it was saying it didn't update existing *values*, and I was confused. Reword the docs to make it clear that `insert()` does update values.

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
Thanks for catching this @tamird. Here's a quick fix. I didn't pick "let the linker link dead code" or "link dead code" because it would add no extra information to the flag name. Here's a another proposal.

Because we no longer use `GetFileAttributesExW` FileAttr is never created directly from `WIN32_FILE_ATTRIBUTE_DATA` anymore. So we should no longer store FileAttr's attributes in that c struct.

Is this what you had in mind?
