Clement Courbet e6b727e552 [X86] Fix VZEROUPPER scheduling info on SNB,HSW,BDW,SXL,SKX. 
Summary:
Starting from SNB, VZEROUPPER is handled by the renamer and uses no proc resources.
After HSW, it also has zero latency.

This fixes PR35606.

To reproduce:
Uops:
  llvm-exegesis -mode=uops -opcode-name=VZEROUPPER
Latency:
  echo -e '#LLVM-EXEGESIS-DEFREG XMM0 1\n#LLVM-EXEGESIS-DEFREG XMM1 1\nvzeroupper' | /tmp/llvm-exegesis -mode=latency -snippets-file=-
  echo -e '#LLVM-EXEGESIS-DEFREG XMM0 1\n#LLVM-EXEGESIS-DEFREG XMM1 1\nvzeroupper\naddps %xmm0, %xmm1' | /tmp/llvm-exegesis -mode=latency -snippets-file=-
