[AArch64] Add support for MSVC-style mangling for SVE (#196738)

Fixes #196170

Recent MSVC toolchains added support for AArch64 SVE types and use
dedicated builtin manglings such as `$_CD` instead of the older
artificial `__clang` struct manglings.

Update Clang's Microsoft mangling implementation to match MSVC for
supported SVE builtin types.

Unsupported SVE types continue using the existing artificial tag
mangling until MSVC gains support for them.

Adds representative coverage for:
* scalar SVE types
* tuple/vector SVE types
* fallback manglings for unsupported types

[CodeGenPrepare] splitMergedValStore: don't split atomic stores. (#199592)

splitMergedValStore notices when you do e.g.

    z = x | (y << 32)
    store z

and may split this up into 32-bit two stores, of x and y, depending
e.g. on the type of x and y.

It skips this optimization for volatile stores, but currently does NOT
skip it for atomics (!!).  So an atomic store can be split up into two
(non-atomic!) stores.

This bug was found by a large run of Opus 4.7 looking for bugs in LLVM.

[RISCV][P-ext] Fold bitcast of v4i8/v2i16 const splat to scalar on RV64 (#199513)

clang lowers `int8x4_t f(int8x4_t a) { return ~a; }` to a
bitcast-wrapped vector xor with splat(-1). v4i8/v2i16 aren't legal on
RV64, so the xor gets scalarized to i64 with the constant still wrapped
in BITCAST:
      `i64 = xor X, (bitcast (v8i8 splat -1))`

The scalar `not` PatFrag (xor X, -1) requires a literal constant and
can't see through BITCAST, so XORI -1 (= `not`) misses and we emit `li
-1; xor` (2 insns). The v8i8/v4i16/v2i32 paths stay at vector level and
match the bitcast-aware vector `vnot` td-pat, so they're fine; only the
widened-from-v4i8/v2i16 path falls through to scalar `not`.

Fix it by folding the bitcast of a v4i8/v2i16 constant splat to a scalar
i32 constant pre-legalization. Type promotion sign-extends to i64 -1 and
XORI matches.

[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.
