  -----------
  [X86] Update SSE/AVX ABS intrinsics to emit llvm.abs.* (PR46851)

We're now getting close to having the necessary analysis/combines etc. for the new generic llvm.abs.* intrinsics.

This patch updates the SSE/AVX ABS vector intrinsics to emit the generic equivalents instead of the icmp+sub+select code pattern.

  Log Message:
  -----------
  [X86][SSE] Move llvm.x86.ssse3.pabs.*.128 intrinsics to ssse3-intrinsics-x86-upgrade.ll

These have been auto upgraded for some time so this is just a tidyup.
