[lldb][NativePDB] Use CV qualifiers from `this` type for methods (#199214)

When we create the Clang types for methods, we ignored the qualifiers.
So `const` methods would become non-const.

With this PR, we use the qualifiers from `*this` for the function type.

[clang] ast-text-dump: fix printing of declref to decomposition with no bindings.

Clang supports empty structured binding groups as an extension,
and the text node dumper has some special handling for giving a name

least one binding.

[SLP] Retry vectorization of FMA candidates after block processing

fadd/fsub instructions that canConvertToFMA returns valid for were
unconditionally skipped in tryToVectorize, causing regressions
where SLP failed to vectorize loops containing such patterns even when
FMA formation never fires.
Collect skipped FMA candidates during vectorizeChainsInBlock and retry
them with AllowFMACandidates=true after all other instructions in the
block have been processed. The cost model still rejects the retry when
actual FMA formation is more profitable (e.g. FMA4 on bdver2), so
existing FMA-profitable cases are unaffected.

Fixes #198040

[flang-rt] Remove library dependency from flang-rt to offload (#198793)

Summary:
We need the offload project's RPC thread to handle the IO requests
originating from the GPU. Previously we did the 'easy' solution and just
linked this handler directly into the offload proejct. This is not ideal
because it prevents people's ability to build and configure libraries
separately.

This PR inverts the dependency, flang-rt now conditionally enables
support using the existing RPC callback mechanism. The cost is that
every flang-rt program now pays the cost of a boolean compare, the
benefit is the libraries are now independent of each-other.

[VPlan] Assert that replacement types match in VPUser::setOperand (NFC). (#195891)

Add assertion to VPValue::setOperand to check if types of the new
operand matches the old operand.

This makes it easier to catch replacements with incorrect types at the
source, instead only later during verification.

A few places currently preform replacements with mis-matching types,
which only get fixed up later. Update those to avoid type-violation.

[mlir][IR] Require token producer and consumer traits

Add marker traits for operations that intentionally produce or consume the
builtin token type. The verifier now rejects token results without
TokenProducerTrait, token operands without TokenConsumerTrait, token entry
block arguments whose parent op does not produce tokens, and token block
arguments outside entry blocks.

Extend the Test dialect token ops to cover valid opt-in cases and each
verifier rejection path.
