linux/futex: Don't load a timeout when try-locking a mutex
linux_sys_futex() does not copyin a timespec for the timeout if the
operation is LINUX_FUTEX_TRYLOCK_PI, presumably because it doesn't make
sense to specify a timeout for a try-lock operation. However, this
means that we pass a userspace timespec pointer to
linux_umtx_abs_timeout_init().
Modify linux_futex_lock_pi() to not initialize the timeout if we're
try-locking.

Differential Revision: https://reviews.freebsd.org/D58061
Reland "Compute GUIDs once and store in metadata" (#184065) (#201849)
This reverts #201194, thus relanding @orodley's PR #184065 (and
#200323):
> This allows us to keep GUIDs consistent across compilation phases
which may change the name or linkage type.
> See
https://discourse.llvm.org/t/rfc-keep-globalvalue-guids-stable/84801
The CFI issues that triggered the original revert are fixed by #201370,
together with the addressing of the TODOs in `LowerTypeTests.cpp` left
in the latter. The [graphite
diff](https://app.graphite.com/github/pr/llvm/llvm-project/201849/Reland-%23184065)
between this change's V1 and V2 shows what's been added:
- the `TODO`s from #201370 are done
- in LowerTypeTests.cpp, passing `!guid` when creating a new declaration
and when converting a definition to a declaration.

Add explicit anchors to deep headers for AMD DWARF ext doc (#208110)
Anchors get auto-generated only upto level 6, and
https://github.com/llvm/llvm-project/pull/208103 added another level,
causing sphinx to complain about no targets for these anchors.
[clang][ARM64X] Support compiling both native and EC objects with -marm64x (#207612)
When -marm64x is used during the assembly phase, construct jobs for both
native and EC targets and merge their outputs using llvm-objcopy.
Allow passing ArchName to computeTargetTriple on non-Darwin targets to
enable BindArchAction on other platforms. Additionally, allow passing
multiple inputs to ObjcopyJobAction and use this capability to construct
ARM64X merge jobs.
kern/sys_process.c: clean up includes
Order them alphabetically.
