Fix a test case that was intermittently failing.  The issue was that instantiations are not stored in an order preserving structure, so the print order may be impacted.  Modified test case to do two FileCheck passes to ensure that both instantiations are in the same place.

Test originially commited at r136306 and temporarily silenced at r136348.
