atf: import atf-0.26
This change imports 0.26 release content from [upstream][1].
The atf-0.26 artifact was been verified by [SHA256 checksum][2].
This update pulls in a large number of memory management fixes, polished upstreamed
content from contrib/atf in FreeBSD (proper), etc.
Please note that this new version requires a C++-20 compatible toolchain
to build.
More information about the release (from a high level) can be found in
the [release notes][3].
Updated via [`update_atf.sh`][4] using `update_atf.sh 0.26 atf-0.26`.

routing: fix ACL patterns for gateway groups (#10909)
Since the conversion in f10505148 the page lives at ui/routing/gateway_groups
and its API at api/routing/group_settings/*, so a user holding only this privilege
sees no Group entry under System: Gateways and receives 403 on every
group_settings call.
[AMDGPU][InstCombine] Canonicalize dot constant operands
Move constant dot product source operands to the right hand side
and add tests for signed and unsigned dot intrinsics.
[AMDGPU][InstCombine] Fold zero dot operands to accumulator
Fold AMDGPU dot intrinsics when either operand is zero.
`dot(a, 0) = 0` and `dot(0, b) = 0`, so replace the intrinsic with its accumulator.
This avoids unrelated clamp and add/sub reassociation cases.
[AMDGPU][InstCombine] Fold constant add/sub into the dot accumulator
`amdgcn.{s,u}dot{2,4,8}(a, b, C) +/- K -> dot(a, b, C +/- K)` when both the
accumulator C and K are constants. The new constant is computed with
wrapping APInt arithmetic to match the non-clamping accumulate.
Only applies when clamp is false (the saturating accumulate does not
reassociate) and the dot has a single use. K - dot is left alone since it
would need the dot product negated.
tests/sys/kern/unix_stream: fix bad assertion
kqueue returns a value != -1 on error. Test for that instead of any
non-zero value to confirm that success was achieved when calling
`kqueue`.
This issue exists with ATF 0.22+ [1].

Share construct contexts for variant reachability
Use AppendDirectiveContextTraits when building reachable directive paths
so semantic checks and lowering apply the same construct-context rules.
This excludes informational directives such as ASSUME while retaining
executable loop transformations and the source order of combined constructs.
Make AppendConstructTraitsForDirective private again and add semantic
tests for TILE, UNROLL, ASSUME, and TEAMS DISTRIBUTE PARALLEL DO. These
complement the existing lowering tests. The ASSUME case detects the old
collector counting an extra position and skipping a required diagnostic.
[RISC-V] Update streamer ArchString in emitTargetFeaturePush()
Previously, RISCVAsmPrinter::emitTargetFeaturePush() only emitted `.option push`
and `.option arch` without updating the streamer's active ArchString. When
emitting an ELF object file directly (`-filetype=obj`),
RISCVTargetELFStreamer::emitDirectiveOptionArch() is a no-op while
emitTargetFeaturePop() resets ArchString back to the pushed ArchString, so
module-level inline assembly and functions with custom `target-features` failed
to emit updated `$x<arch>` mapping symbols.
Call RTS.setArchString() with the parsed ISA string in emitTargetFeaturePush()
so `-filetype=obj` records the active `$x<arch>` mapping symbol alongside
`.option arch`.

[LTO] Preserve module inline asm target properties for .lto_discard and symvers
Previously, LTO::addRegularLTO() and IRLinker::run() called
prependModuleInlineAsm() and appendModuleInlineAsm() with a plain string when
synthesizing `.lto_discard` and imported `.symver` directives, creating a new
GlobalAsmFragment with empty TargetCPU and TargetFeatures instead of preserving
the existing module inline asm's properties. Copy the front fragment's Props so
these synthesized directives are merged into the module's inline asm with the
same target features.

[AMDGPU] Constant folding for wave-reduce intrinsics (#212755)
Relates to: https://github.com/llvm/llvm-project/pull/193142
A missed optimization opportunity.
While most constants to `add`, `sub` and `xor` wave reductions
cannot be folded, some identity constants(0, 1) can do with
some special handling.
