gcc6-pr68662.patch

So what about this untested patch?  ASM_GENERATE_INTERNAL_LABEL doesn't look to
be too expensive to do unconditionally once, and for GC sanity it needs to go
through ggc_strdup anyway (it is invalid to refer to non-GC allocated strings
in GTY const char * fields that are not skipped by GC).
