New API for disappearing links registration accepting interior pointers
GC_GENERAL_REGISTER_DISAPPEARING_LINK_SAFE() and
GC_REGISTER_LONG_LINK_SAFE() macros are provided.
* include/gc/gc.h (GC_GENERAL_REGISTER_DISAPPEARING_LINK_SAFE,
GC_REGISTER_LONG_LINK_SAFE): New API macros.
* include/gc/gc.h [GC_DEBUG] (GC_GENERAL_REGISTER_DISAPPEARING_LINK):
Use GC_GENERAL_REGISTER_DISAPPEARING_LINK_SAFE() instead of
GC_general_register_disappearing_link() and GC_base() directly.
* include/gc/gc.h [GC_DEBUG] (GC_REGISTER_LONG_LINK): Use
GC_REGISTER_LONG_LINK_SAFE() instead of GC_register_long_link() and
GC_base() directly.
