Simon Pilgrim a7bcd72c0a [X86] Replace VPCOM/VPCOMU with generic integer comparisons (clang) 
These intrinsics can always be replaced with generic integer comparisons without any regression in codegen, even for -O0/-fast-isel cases.

Noticed while cleaning up vector integer comparison costs for PR40376.

A future commit will remove/autoupgrade the existing VPCOM/VPCOMU llvm intrinsics.

Simon Pilgrim 6c38e71476 [X86][XOP] Add codegen tests for vector integer comparison intrinsics (PR15844) 
We were testing for the generic _mm_com_* intrinsics, but not the specific comparison mode versions.
