  Changed paths:
    M clang/lib/Basic/Targets/X86.cpp

  Log Message:
  -----------
  AMD k8 family does not support SSE4.x which are required by x86-64-v2+

So don't define __tune__k8__ for these micro architecture.

SSE, SSE2 and SSE3 appear in https://www.amd.com/system/files/TechDocs/25112.PDF
but not SSE4.x.
