[flang][OpenMP] Lower target in_reduction for host fallback
Enable host-fallback lowering for target in_reduction in Flang and MLIR OpenMP translation.
Model target in_reduction through the matching map entry, force address-preserving implicit mapping for Flang in_reduction list items, and emit the host-side task-reduction lookup with __kmpc_task_reduction_get_th_data. The runtime entry point takes and returns a generic, default-address-space pointer, so normalize a non-default-address-space captured pointer to the generic address space before the call and cast the returned private pointer back to the map block argument's address space, mirroring the in_reduction handling on omp.taskloop. Unsupported device/offload-entry and richer reduction forms remain diagnosed.
Add Flang lowering, MLIR verifier/translation, and LLVM IR tests for the supported host-fallback path, including a non-default-address-space case, and the remaining unsupported cases.
[llvm-debuginfo-analyzer] Add support for LLVM IR format. (#202120)
llvm-debuginfo-analyzer is a command line tool that processes debug
info contained in a binary file and produces a debug information
format agnostic “Logical View”, which is a high-level semantic
representation of the debug info, independent of the low-level format.
Add support for the LLVM IR format and be able to generate logical
views. Both textual representation (.ll) and bitcode (.bc) formats
are supported.

xmlto: apply two shell-related tweaks
First, make shell code used in the "-o" option parsing more portable.
"type -p" hasn't been supported by NetBSD's sh since 8.0 (and also
isn't universally supported elsewhere by other shells). This addresses
PR pkg/60388 from Andrew Cagney. (Really here we're suppressing a
warning rather than a failure, one that happens to show up in build
logs.)
(We could substitute "command -v" instead (recommended over bare "type"
by a NetBSD shell guru), but since both the existing upstream code and
a bunch of our patches are already using "type" in many places, I kept
it consistent here.)
Next, Makefile r. 1.32 removed bash as a runtime dependency, but didn't
account for REPLACE_BASH still being defined, which results in a broken
(though effectively harmless) substitution to "#!". (Here perhaps the
pkgsrc replacement mechanism could be improved so it generates an error
when the replacement path is empty.) This is only relevant for the test
target.

[Clang][Modules] Skip anonymous declaration numbering for local tags in dependent contexts (#202248)
Local tag declarations (classes, structs, enums, and lambdas) defined
within function template bodies or class templates do not require ODR
merging at the local declaration level across different modules. ODR
consistency is already guaranteed because the instantiator only walks
the canonical template definition body, which instantiates its own copy
of the local class.
Merging them across different modules causes their member definitions
(like methods or call operators) to be canonicalized to one module,
while the instantiator walks the template body from another module.
Since local variables within template bodies are not merged, this
mismatch leads to assertion crashes during template instantiation in
`LocalInstantiationScope::findInstantiationOf`.
Fixes https://github.com/llvm/llvm-project/issues/206203.

[X86] Verify inline-asm register operands against the subtarget
Inline asm can name physical registers that require a subtarget feature
the selected subtarget lacks: zmm and mask (k) registers need AVX-512,
ymm registers need AVX. The subtarget is derived from the function's
target-cpu/target-features, so no MachineFunction is required.

[AsmMatcher] Report a near-miss when all candidates mismatch multiple operands (#206390)
In the ReportMultipleNearMisses path, an opcode that mismatches more
than one operand is dropped, and its first near-miss is dropped with it. If
every opcode is dropped this way, the parser only reports a generic
"invalid instruction".
Now keep the first near-miss of each such opcode, and use it only when
no other opcode gives a near-miss.

[TargetParser][NFC] Make FeatureBitset iterable (#206394)
FeatureBitset had no way to iterate its bits, so callers scanned all

unset bits with countr_zero.
Callers can now write `for (unsigned Feature: Features)`.

[lldb][test] Skip more unsupported tests on WebAssembly (#206857)
These tests exercise functionality that WebAssembly does not provide, so
they cannot pass under the Wasm test configuration. The reasons vary by
test, captured by a short inline comment.
Skip them with @skipIfWasm (and @skipIfNoSignals for the SIGINT test) so
the suite reflects real failures.
[clang][llvm]Uncorrelate CFI and Callgraph related type metadata annotations (#204266)
When -fexperimental-call-graph-section flag is set, it adds type
metadata to all the functions whose addresses are taken and does not
have local linkage. When this flag is set along with CFI, the type
metadata is added to all the vtable functions including destructors.
This changes which functions are to be treated as CFI functions and
includes such vtable entries to become part of the CFI check jumptables.
To disambiguate intentions of CFI and callgraph mechanisms, this patch
renames metadata set by callgraph mechanism to !callgraph
(MD_callgraph). This prevents inflating the list of CFI functions when
callgraph section is enabled along with CFI.
