[mlir-c] Add structural operation equivalence (#206537)
Exposes `OperationEquivalence` through the MLIR C API so callers can compare operations structurally rather than by handle identity.

[lld][MachO] Avoid quadratic iteration over already-folded symbols during ICF (#213339)
`ConcatInputSection::foldIdentical()` clears the folded functions
`originalUnwindEntry`.
However, it cleared every symbol: with N members, the repeated clearing
is **O(N²)**.
This is redundant: we should only remove the incoming `copy->symbols`.
This patch moves the removing loop ahead and adds more clear comments on
why we need to skip the first element.
Also added a new `lld/test/MachO/icf-scale-same-class.s` with 500K
identical functions as a stress test, which would've taken minutes to
link, and less than a second with the patch.
Testing on real-world app (IRPGO instrumentation + ICF) find that we
achieved a 19x speed up (1:14:42 -> 3:55)
clang/AMDGPU: Require 16-bit-insts for half typed image builtins
Typed image load/store operations with 16-bit elements require d16
support which was introduced in gfx8. They were previously gated only
on image-insts, so they were wrongly accepted on targets that have
images but lack 16-bit support (e.g. gfx700), where the backend then
fails to select.

clang/AMDGPU: Require 16-bit-insts for half typed buffer format builtins
Typed buffer format load/store operations with 16-bit elements require
d16 support which was introduced in gfx8. These builtins previously had
no required features at all, so they were accepted (and then crashed the
backend) on targets without 16-bit support.
Diagnose these in Sema, parallel to the image builtins. The manual
verification here suprised me. The automatic builtin feature verification
is enforced in codegen, which seems like a layering violation which
should be fixed.

clang: Replace Is*OffloadArch free functions with OffloadArch methods
Drop the IsNVIDIAOffloadArch/IsAMDOffloadArch/IsIntel*OffloadArch free
functions in favor of the OffloadArch member predicate functions.

[InstSimplify] Defer to ConstantFold in simplifyInstrinsic (#205061)
Defer to ConstantFolding on all-constant operands, in
llvm::simplifyIntrinsic. The patch adds a context-function argument to
ConstantFoldIntrinsic for strictfp information, which is used by a new
canConstantFoldIntrinsic under canConstantFoldCallTo: it was
necessitated by exposing the constant-folder via
llvm::simplifyIntrinsic. The patch only has impact on passes that use
simplifyIntrinsic via InstSimplifyFolder, other than InstCombine, which
already constant-folds intrinsics.
