[RISCV] Support MachineOutlinerRegSave for RISCV (#191351)
This patch adds support for the RegSave strategy in the RISC-V
MachineOutliner pass. It uses t1–t6 to preserve the t0 value across the
outlined function call when t0 is unavailable. This enables more
potential outlining candidates.

CI: Do not set scheduler in qemu-1-setup.sh
We've seen some qemu-1-setup failures while trying to change the
runner's block device scheduler value to 'none':
We have a single 150GB block device
Setting up swapspace version 1, size = 16 GiB (17179865088 bytes)
no label, UUID=7a790bfe-79e5-4e38-b208-9c63fe523294
tee: '/sys/block/s*/queue/scheduler': No such file or directory
Luckily, we don't need to set the scheduler anymore on modern kernels:
https://github.com/openzfs/zfs/issues/9778#issuecomment-569347505
This commit just removes the code that sets the scheduler.

[DAGCombiner] Extend convertBuildVecZextToZext to sign extends (#192372)
Generalize the existing fold that collapses a BUILD_VECTOR of ZERO_EXTEND
(or ANY_EXTEND) of EXTRACT_VECTOR_ELTs into a single vector extend so that
it also handles SIGN_EXTEND. Mixed sign and zero extends remain unsupported
because their high-bit semantics differ, so the combine bails out in that
case.

15.1: Update stable/15 to -PRERELEASE
This marks the start of the FreeBSD 15.1 release cycle; the stable/15
tree is now in "code slush".
Developers are encouraged to prioritize fixing bugs (and/or merging bug
fixes from HEAD) over new features at this time. Commit approval from
re@ is not required but if new features introduce problems they may be
removed from the release.

[AMDGPU] Add `.amdgpu.info` section for per-function metadata
AMDGPU object linking requires the linker to propagate resource usage
(registers, stack, LDS) across translation units. To support this, the compiler
must emit per-function metadata and call graph edges in the relocatable object
so the linker can compute whole-program resource requirements.
This PR introduces a `.amdgpu.info` ELF section using a tagged, length-prefixed
binary format: each entry is encoded as:
```
[kind: u8] [len: u8] [payload: <len> bytes]
```
A function scope is opened by an `INFO_FUNC` entry (containing a symbol
reference), followed by per-function attributes (register counts, flags, private
segment size) and relational edges (direct calls, LDS uses, indirect call
signatures). String data such as function type signatures is stored in a
companion `.amdgpu.strtab` section.

[CIR][NFC] Upstream IR roundtrip tests for branch and loop ops (#189006)
Add `clang/test/CIR/IR` roundtrip tests for `cir.br`, `cir.brcond`,
`cir.for`, `cir.while`, and `cir.do`.
This adds parser/printer coverage for the textual forms of these
control-flow operations.
Partially addresses #156747.
[flang][cuda] Add missing pointer deallocation entry point (#192566)
We were missing the deallocation entry point for pointer and wiring all

ZTS: resilver_restart_001 improvements
The resilver_restart_001 test case has not been entirely reliable
when run under the CI. Address several small issues which may be
responsible.
- Configure the pool as raidz2 instead of raidz1 since the test
offlines two devices. This ensures the second device is marked
as OFFLINE instead of DEGRADED.
- Start the zpool replace after setting SCAN_SUSPEND_PROGRESS to
close any potential race where the replace finishs to quickly.
- Wait for the offlines/onlined vdevs to fully transition to the
expected state during the test.
- Add the true flag to sync_pool to force a TXG sync to happen
even if it might not otherwise be required.

[NFC][OpenMP] Make map ordering tests for no host->tgt transfer more robust (#192571)
They were relying on the host value not being seen on the device, but
the value being matched was small enough for the probability of a
successful match against garbage data relatively high.
Now we just rely on the LIBOMPTARGET_DEBUG logs to ensure there wasn't
any transfer.
