This is just the basic groundwork for supporting DW_TAG_imported_module but I wanted to commit this before pushing support further into Clang or LLVM so that this rather churny change is isolated from the rest of the work. The major churn here is obviously adding another field (within the common DIScope prefix) to all DIScopes (files, classes, namespaces, lexical scopes, etc). This should be the last big churny change needed for DW_TAG_imported_module/using directive support/PR14606. llvm-svn: 178099
