This test/CodeGen/builtins-ppc-p9vector.c test will fail together with this upcoming LLVM patch https://reviews.llvm.org/D24955

Problem is that lots of your

  add i64 {{.*}}, 64

checks will fails since the improved analysis will find out that the add has the "nsw" "nuw" properties.

I'm not so familiar with the regexps used by FileCheck, but somehow we need to (also) allow

  add nsw nuw i64 {{.*}}, 64

in the checks to make it more future proof.
