Summary: Until we find a decent heuristic on how to choose between multiple identical trees, there is no point in supporting multiple mappings. This also enables matching of nodes with parents of different types, because there are many instances where this is appropriate. For example for and foreach statements; functions in the global or other namespaces. Reviewers: arphaman Subscribers: klimek Differential Revision: https://reviews.llvm.org/D36183 llvm-svn: 311251
