in the context in which it was originally found, the expression parser now goes hunting for it in all modules (in the appropriate namespace, if applicable). This means that forward-declared types that exist in another shared library will now be resolved correctly. Added a test case to cover this. The test case also tests "frame variable," which does not have this functionality yet. llvm-svn: 146204
