Fixes the issue highlighted in http://lists.llvm.org/pipermail/cfe-dev/2014-June/037500.html. The DW_AT_decl_file and DW_AT_decl_line attributes on namespaces can prevent LLVM from uniquing types that are in the same namespace. They also don't carry any meaningful information. rdar://problem/17484998 Differential Revision: https://reviews.llvm.org/D32648 llvm-svn: 301706
