PR modula2/111627 defend against ICE

Browse source 
Although PR 111627 can be fixed by renaming testsuite modules it
highlighted that a possible ICE can occur if a malformed
implementation module is actually a program module.  This small
patch defends against this ICE and checks to see whether the module
is a DefImp before testing IsDefinitionForC.
