This changes the behavior of AddAligntmentAssumptions to match its comment. I.e, prove the asserted alignment in the context of the caller, not the callee. Thanks to Mehdi Amini for seeing the issue here! Also to Artur Pilipenko who also saw a fix for the issue. rdar://22521387 Differential Revision: http://reviews.llvm.org/D12997 llvm-svn: 248390
