Do not add extra byte to non-small uncollectible objects
Previously EXTRA_BYTES value was not added to the allocation size only
for small uncollectible objects.
* include/gc/gc.h (GC_all_interior_pointers): Refine comment (regarding
uncollectible objects).
* malloc.c (GC_generic_malloc_uncollectable): Define lb_orig local
variable; decrement lb before if(SMALL_OBJ(lb)); do not expect original
lb is zero; pass lb_orig (instead of lb) to GC_DBG_COLLECT_AT_MALLOC()
and to oom_fn().
