Sanjay Patel bcc5ed7b24 [CodeGen] fix test to be (mostly) independent of LLVM optimizer; NFC 
This test would break with the proposed change to IR canonicalization
in D79171. The raw unoptimized IR from clang is massive, so I've
replaced -instcombine with -mem2reg to make it more manageable,
but still be unlikely to break with unrelated changed to optimization.

Fangrui Song dbc96b518b Revert "[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition" 
This reverts commit 789a46f2d7.

Accidentally committed.

Fangrui Song 789a46f2d7 [CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition 
Summary:
Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults
to -fsemantic-interposition).
Users need to specify -fsemantic-interposition to get semantic
interposition behavior.

Semantic interposition is currently a best-effort feature. There may
still be some cases where it is not handled well.

Ahmed Bougacha b26fa705df [AArch64] Change size suffix for FP16FML intrinsics. 
These currently use _u32, but they should instead use _f16, the
types of the multiplication (matching the various integer vmlal
variants).

Bryan Chan 223307b3dc [AArch64] Implement FP16FML intrinsics 
Generate the FP16FML intrinsics into arm_neon.h (AArch64 only for now).
Add two new type modifiers to NeonEmitter to handle the new prototypes.
Define __ARM_FEATURE_FP16FML when +fp16fml is enabled and guard the
intrinsics with the macro in arm_neon.h.

Based on a patch by Gao Yiling.
