FAIL: g++.old-deja/g++.abi/cxa_vec.C execution test

This test fails with the new dwarf eh support.  It shouldn't fail with
sjlj exceptions.

I've looked at the failure in some detail.  The problem is this test
overloads new.  By somewhat unlucky circumstances, get_file_function_name_long
chooses the same symbol name for the fde in the cxa_vec and an object
in libstdc++.sl.  This breaks the fde search for libstdc++.

collect2_eh_frame_section calls get_file_function_name with kind, 'F'.
This isn't documented as one on the types for get_file_function_name.
Anyway, I don't think the first_global_object_name is suitable for
this type.
