The function importer was still materializing metadata when modules were loaded for function importing. We only want to materialize it when we are going to invoke the metadata linking postpass. Materializing it before function importing is not only unnecessary, but also causes metadata referenced by imported functions to be mapped in early, and then not connected to the rest of the module level metadata when it is ultimately linked in. Augmented the test case to specifically check for the metadata being properly connected, which it wasn't before this fix. llvm-svn: 257171
