musman updated the diff for D83392: Strlen loop idiom recognition.

Change to use SCEV instead of pattern match for strlen recognition.

Hi @efriedma, I am having some trouble understanding how to transform the AddRec to Add ({n,+,1} to n + strlen(p)). Should this be done with ScalarEvolution::getAddExpr, and then expanded? Thanks.

@efriedma Thanks for the review, I didn't think to use SCEV for this. I will modify the code as you suggested.
