[mlir][OpenACC] Lower single-block thread-only array reductions (#212369)
Example:
```fortran
!$acc parallel loop vector reduction(+:b)
do i = 1, n
b(i) = i
end do
```
In this code the array reduction is thread(vector)-only with no
gang/block launch dim, so a within-block `all_reduce` is a complete
reduction. ACCCGToGPU still rejected it as NYI because the accumulate
had no block context.
Fix: keep the NYI only when the region actually launches block
dimensions; allow the existing per-element `all_reduce` path for
single-block thread-only array accumulates.
emulators/Ymir: Fix build after semver update
The function semver::detail::compare_parsed dropped the third argument,
with the former value being the default for normal comparisons now.
While there add libfreetype.so to LIB_DEPENDS because x11-toolkits/imgui
enabled the FREETYPE option by default recently.

[NVPTX] Emit some more PTX directives through target streamer (#212070)
Move `.branchtargets`, `.reg`, `.local`, `.alias`, `.pragma`, and the
empty `.debug_macinfo` section out of hand-built strings in
`NVPTXAsmPrinter` and into `NVPTXTargetStreamer` hooks.
Opportunistically pulled at a few other threads that could use cleanup
as well.
Three behavior changes:
1. Jump table labels now come from `MachineFunction::getJTISymbol`, so
`$L_brx_<idx>` becomes `JTI<func>_<idx>` and is no longer shared across
functions
2. `.alias` names its aliasee by mangled symbol rather than raw IR name,
fixing `.alias a, ;` for an unnamed aliasee.
3. The rest of the test diff is a duplicated blank line that functions
with no register declarations no longer emit.

[MacroFusion] Add RunPreRA/RunPostRA to select the scheduling stage (#212182)
MacroFusion runs in both the pre-RA and post-RA machine schedulers.
Add two `bit` fields to the `Fusion` base class, `RunPreRA` and
`RunPostRA`, both defaulting to `true`, so a fusion can opt out of a
scheduling stage. At least one of them must be `true`.
When a stage is disabled, `MacroFusionPredicatorEmitter` emits an early
`return false` guard for that stage (detected via the `NoVRegs` machine
function property) and only keeps the statistic counter for the stage
the fusion actually runs in. A pre-RA-only fusion is generated as:
```cpp
STATISTIC(NumNAMEPreRA, "Times NAME Triggered (pre-ra)");
bool isNAME(...) {
...
if (SecondMI.getMF()->getProperties().hasNoVRegs())
return false;
/* Predicates */

Revert "tests/ktls: merge two sysctl checking helpers into one"
With certain sysctl configuration the test will fail.

RELNOTES: Add an entry for pNFS server improvements
There are expected to be additional improvements and this RELNOTES
entry will be updated accordingly.
make-pkg-package.sh: Fix build for pkg 2.8.0
We used to pass CONFIGURE_ARGS to the make command which builds pkg,
but ports/ports-mgmt/pkg/Makefile has its own CONFIGURE_ARGS and the
version we were providing at the command line didn't contain the
--mandir setting which was added to the port with pkg 2.8.0. This
broke release builds.
Instead of passing --prefix=${LOCALBASE} via CONFIGURE_ARGS, pass
PREFIX=${LOCALBASE}; the port Makefile passes that value through to
its configure script. We also used to pass a --host parameter, but
that seems to have become unnecessary at some point in the past decade.

[llvm-objcopy] Add AMDGPU case to binary-output-target.test
Add test coverage for converting binary input to elf64-amdgpu format,
verifying the output has the correct format string, arch (amdgpu),
and machine type (EM_AMDGPU 0xE0). Follows the same pattern as all
other architectures in this test file.
[llvm-objcopy] Fix AMDGPU arch checks in tests
ELFObjectFile.h getArch() for EM_AMDGPU returns Triple::UnknownArch
when e_flags & EF_AMDGPU_MACH is 0 (no GPU target specified). Only
when a MACH flag in the AMDGCN range is present does it return
Triple::amdgpu.
- cross-arch-headers.test: restore EF_AMDGPU_MACH_AMDGCN_GFX900 flag
on the input ELF so that after format conversion the output correctly
reports Arch: amdgpu.
- binary-output-target.test: expect Arch: unknown since converting
from raw binary input (-I binary) produces an ELF with e_flags=0
(no MACH flags), giving UnknownArch. This is correct behavior.
[SLP]Fix dep accounting for expanded binops in non-scheduled entries
The extra dependency counted for the expanded form was never released
when the expanding entry had no schedule bundle and the block had no
copyable elements, leaving the operand's bundle unscheduled forever.
Take the pseudo-bundle path also when the instruction is an expanded
binop in some tree entry.
