[PowerPC][Clang] Remove QPX support

[jsji]

Summary

Clean up QPX code in clang missed in https://reviews.llvm.org/D83915

[qiucf]

Another small place also needs remove? (but not related to clang)

llvm/test/Transforms/LoopVectorize/PowerPC/vectorize-only-for-real.ll:

attributes #0 = { nounwind "target-cpu"="a2q" "target-features"="+qpx,-altivec,-bpermd,-crypto,-direct-move,-extdiv,-power8-vector,-vsx" }
attributes #1 = { argmemonly nounwind }
attributes #2 = { "target-cpu"="a2q" "target-features"="+qpx,-altivec,-bpermd,-crypto,-direct-move,-extdiv,-power8-vector,-vsx" }
attributes #3 = { nounwind }

[jsji]

Fix llvm test as well

[steven.zhang]

LGTM as I grep the whole repo with this patch applied, no QPX any more.
