[flang-rt] Fix defining `pid_t` on GPU builds (#178470)

Summary:
We support building flang-rt on GPU targets. These do not have POSIX
types so we should not include this if it's not present.

NAS-139295 / 26.0.0-BETA.1 / Add umount utility (#18016)

This commit exposes truenas_os.umount2 as an available utility in
mount.py, and replaces existing subprocess calls to the umount command
with the syscall-based utility.

[mlir][dataflow ] Drop LLVM_DEBUG of DATAFLOW_DEBUG (NFC) (#177398)

We kept the DATAFLOW_DEBUG macro because when
LLVM_ENABLE_ABI_BREAKING_CHECKS is 0, the debugName in AnalysisState is
not defined, which prevents us from printing debug logs(In this case, we
define DATAFLOW_DEBUG(X) as an empty macro, so it won't print any logs).
Therefore, this PR only removes LLVM_DEBUG. We are now using LDBG, so
LLVM_DEBUG is no longer needed.

[clang][constexpr] Move inf/nan/denormal handling into FP binop callbacks (#178421)

Update the callback signature for `EvaluateFpBinOpExpr` and
`interp__builtin_elementwise_fp_binop` to return
`std::optional<APFloat>`, allowing individual callbacks to decide
whether to handle special floating-point cases (inf/nan/denormal).

Previously, the helper functions had hardcoded validation that forced
all callbacks to reject these cases. This blocked intrinsics needing
custom validation (e.g., rounding mode checks). Now each callback
controls its own validation and returns `std::nullopt` when the fold is
invalid.

Fixes #178416

[AArch64][llvm] Allow some `tlbip` insns to be used with only +tlbid

Allow `tlbip` instructions containing *E1IS*, *E1OS*, *E2IS* or *E2OS*
to be used with `+tlbid` or `+d128`. This is because the 2025 Armv9.7-A
MemSys specification says:

```
All TLBIP *E1IS*, TLBIP*E1OS*, TLBIP*E2IS* and TLBIP*E2OS* instructions
that are currently dependent on FEAT_D128 are updated to be dependent
on FEAT_D128 or FEAT_TLBID
