Andreas Arnez e0c0f156b4 Exploit 'prepare_for_testing' etc. for 'Dwarf::assemble'-generated files
Now that prepare_for_testing etc. can cope with absolute path names,
this can be exploited for test cases with generated source files.
This is just to simplify the code and shouldn't cause any functional
change.
