[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.
