Now when I try to rebuild GCC build fails with error:

See also the gengtype.c file, and the doc/gty.texi file.
I'm just guessing, but you probably either need to add a GTY marker to
the struct pointer_set_t definition, or else add a GTY skip marker to
the new field in struct basic_block_def that uses the pointer_set_t
type. It depends on whether this info will be allocated in the garbage
collection space (e.g. ggc_alloc).
