[MCP] Early exit if no copies (NFC) (#201602)
These two functions do expensive per-regunit work, but are no-ops if
there are no Copies, so short-circuit this case.
Include AArch64 SME builtins to compiler-rt for Bazel. (#196607)
Include the AArch64 SME (Scalable Matrix Extension) source files in the
compiler-rt builtins library when targeting aarch64. Added a selection

NAS-141124 / 27.0.0-BETA.1 / Prevent VMs being suspended indefinitely after periodic snapshots (by creatorcary) (#19062)
## Problem
VMs with disks on a dataset covered by a periodic snapshot task could be
left indefinitely in the libvirt `PAUSED` (`SUSPENDED`) state,
recoverable only via `vm.resume` or a host reboot. Two independent bugs
combined to cause this.
## Bug 1: `suspend_on_snapshot` was ignored for running VMs
`vm.suspend_vms` suspended every running VM whose disk was on the
snapshotted dataset, regardless of the per-VM `suspend_on_snapshot`
setting. The opt-out filter in `query_snapshot_begin` (`status NOT IN
active AND suspend_on_snapshot = False`) only ever excluded *stopped*
VMs, so it was a no-op for the running VMs that actually get suspended.
Fix: gate suspension in `suspend_vms` on `RUNNING and
suspend_on_snapshot`. The filter is left in `suspend_vms` rather than

Serialize rootfs read-only/sysext toggles with a shared lock
Remove the ability for concurrent calls to do things with root
filesystem unlocked (either administratively through
disable-rootfs-protection) or internal middleware callers that
do things in /usr to clobber each other.
Protection takes belt-and-suspenders approach of taking pthread
lock, then taking flock.
[Clang] Correct diagnostic notes for C++11 range-based for statements with invalid iterator types (#201461)
Previously, diagnostic notes issued for errors encountered due to invalid
iterator types in C++11 range-based for statements reported the range type
as the iterator type instead of the invalid iterator type. Now fixed.
[AArch64][GlobalISel] Add pattern to prevent scalar uqxtn fallback (#201546)
Previously, attempting to select the intrinsic
@llvm.aarch64.neon.scalar.uqxtn would cause GlobalISel to fall back to
SDAG.
This was both due to:
1. RegBankSelect placing the operands on gpr banks.
2. No instruction selection patterns for the intrinsic.
Add pattern, and fix RegBankSelect to place operands on the correct
banks.
[RISCV][P-ext] Support packed bswap/bitreverse. (#200448)
We can implement these using combinations of rev, rev8, and ppairoe.*.
Rename REV16->REV16_RV64. A hypothetical REV16 on RV32 would have a
different encoding like REV and REV8.
Long term we should probably custom lower these instead of having
complex isel patterns. That would allow additional optimizations. But I
think the isel patterns are fine as a starting point.
[Clang][Docs] Documented sentinel attribute (#196088)
The documentation of the sentinel attribute was missing, this PR
documents the behavior of the sentinel attribute.
[Bazel]: Pull from Bazel-Central-Registry for third party deps. (#197316)
The majority of these dependencies are available in the
[Bazel-Central-Registry](https://github.com/bazelbuild/bazel-central-registry)
(BCR) and to improve build performance for bzlmod users, llvm-project
should pull from the BCR to consolidate targets.
[X86] Fix MachineBlockInfo hash for machine-block-hash.mir (#201039)
I looked at llvm/include/llvm/CodeGen/MachineBlockHashInfo.h,
BlendedBlockHash function and rewrote failing test.

ObsoleteFiles: Add some ancient locale symlinks
These were dropped in 2021 but were never listed in ObsoleteFiles.inc,
so systems that have been upgraded from source since before that date
