Sanjay Patel b155a7cf56 [InstCombine] call simplify before trying vector folds ...

As noted in the review thread for rL333782, we could have
made a bug harder to hit if we were simplifying instructions
before trying other folds. 

The shuffle transform in question isn't ever a simplification;
it's just a canonicalization. So I've renamed that to make that 
clearer.

This is NFCI at this point, but I've regenerated the test file 
to show the cosmetic value naming difference of using 
instcombine's RAUW vs. the builder.

Possible follow-ups:
1. Move reassociation folds after simplifies too.
2. Refactor common code; we shouldn't have so much repetition.
