This revision is now accepted and ready to land.

You can test by adding a test in `test/tools/llvm-exegesis/X86/uops/` with something like:

  # RUN: llvm-exegesis -mode=uops -opcode-name=ADDPSrr -repetition-mode=duplicate | FileCheck --check_prefix=ALL_REGS %s
  # RUN: llvm-exegesis -mode=uops -opcode-name=ADDPSrr -repetition-mode=duplicate -x86-disable-upper-sse-registers | FileCheck --check_prefix=LOW_REGS %s
  
  ALL_REGS:   XMM15
  LOW_REGS-NOT:   XMM15
