d929146b - [Clang][AArch64] Lower NEON vaddv/vminv/vmaxv builtins to llvm.vector.reduce intrinsics. (#165400)

[Clang][AArch64] Lower NEON vaddv/vminv/vmaxv builtins to llvm.vector.reduce intrinsics. (#165400) This is the first step in removing some NEON reduction intrinsics that duplicate the behaviour of their llvm.vector.reduce counterpart. NOTE: The i8/i16 variants differ in that the NEON versions return an i32 result. However, this looks more about making their code generation convenient with SelectionDAG disgarding the extra bits. This is only relevant for the next phase because the Clang usage always truncate their result, making llvm.vector.reduce a drop in replacement.
