Summary: I searched Transforms/ and Analysis/ for 'ByVal' and updated those call sites to check for inalloca if appropriate. I added tests for any change that would allow an optimization to fire on inalloca. Reviewers: nlewycky Differential Revision: http://llvm-reviews.chandlerc.com/D2449 llvm-svn: 200281
