gcc6-pr69518.patch
Untested fix. The problem is that when type variants are created, the generic
code copies there also the TYPE_VFIELD aka C_TYPE_INCOMPLETE_VARS. We clear it
only in the main type variant, but not in other variants, so if not anything
else, it is at least undesirable for GC purposes, plus we leak the C FE use of
that field into the middle-end.
