Regression: runaway allocation of heaps.

* gc.c (make_obj): Fix regression introduced on 2014-10-18,
released in TXR 100. Because make_obj discontinues
placing objects into the freshobj_array when the full_gc
flag has been set, it is incorrect to allocate another heap
when the free list is exhausted and the freshobj_array
has room remaining. It has room remaining because it is
disused.
