Benjamin Kramer 5259bbde82 Make CHECK lines a bit less strict so they also match code generated for win64. 
Hopefully brings the windows buildbots back to life.

Benjamin Kramer aec90531f9 X86: Now that we have a canonical form for vector integer abs, match it into pabs.

Benjamin Kramer d56ffc709d DAGCombiner: Canonicalize vector integer abs in the same way we do it for scalars. 
This already helps SSE2 x86 a lot because it lacks an efficient way to
represent a vector select. The long term goal is to enable the backend to match
a canonicalized pattern into a single instruction (e.g. vabs or pabs).
