* Create a USR for the occurrences of the 'module' symbol kind
* Record module references for each identifier in an import declaration
llvm-svn: 342484
Whether we call an ImportDecl a decl or a reference symbol role is
somewhat academic, but in practice it's more like a declaration because
it is interesting even to consumers who wouldn't care about references.
Most importantly, we want to report the module dependencies of system
modules even when we have declaration-only filtering.
