The original change broke clang side tests. I will be submitting those momentarily. This change includes post commit feedback on the original change from from Pete Cooper. Original Submission comments: If a parameter to a function is known non-null, use the existing parameter attributes to record that fact at the call site. This has no optimization benefit by itself - that I know of - but is an enabling change for http://reviews.llvm.org/D9129. Differential Revision: http://reviews.llvm.org/D9132 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@239849 91177308-0d34-0410-b5e6-96231b3b80d8
