When preserving noalias function parameter attributes by adding noalias metadata in the inliner, we should do this for general function calls (not just memory intrinsics). The logic is very similar to what already existed (except that we want to add this metadata even for functions taking no relevant parameters). This metadata can be used by ModRef queries in the caller after inlining. This addresses the first part of PR20500. Adding noalias metadata during inlining is still turned off by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@215657 91177308-0d34-0410-b5e6-96231b3b80d8
