[Clang] Add `__builtin_stack_address` (#148281)
Add support for `__builtin_stack_address` builtin. The semantics match
those of GCC's builtin with the same name.
`__builtin_stack_address` returns the starting address of the stack
region that may be used by called functions. It may or may not include
the space used for on-stack arguments passed to a callee (See [GCC
Bug/121013](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121013)).
Fixes #82632.

regress/xstate: Dynamic xstate buffer size
The current implementation leads to an "xstate buffer too small" error
on newer machines with an xstate area bigger than 1KiB. Allocate the
buffer dynamically from PT_GETXSTATE_INFO kernel info.

github: Add more context to pull requests
Add code to fetch and decode CODEOWNERS and automatically @ people in
the review.
Create a new file, .github/path-rules.txt that has a set of paths to
match and specific warnings about that part of the tree. We'll use this
to try to wave off pull requests in certain areas of the tree, as well
as remind people when contrib is involved, etc.

[clang] fix warning (#174587)

[PowerPC] Optimize not equal compares against zero vectors (#150422)
This patch is for special cases involving 0 vectors. During the
comparison of vector operands, current code generation checks with
`vcmpequh (vector compare equal unsigned halfword)` followed by a
negation `xxlnor (VSX Vector Logical NOR XX3-form)`.
This means that for the special case, instead of using `vcmpequh` and
then negating the result, we can directly use `vcmpgtuh (vector compare
greater than unsigned halfword)`.
As a result the negation is avoided since the only condition where this
will be false is for 0 as it is an `unsigned halfword`.
