  Log Message:
  -----------
  [WebAssembly] SIMD integer min and max instructions

Summary:
Introduces a clang builtins and LLVM intrinsics representing integer
min/max instructions. These instructions have not been merged to the
SIMD spec proposal yet, so they are currently opt-in only via builtins
and not produced by general pattern matching. If these instructions
are accepted into the spec proposal the builtins and intrinsics will
be replaced with normal pattern matching.
