Code cleanup.

* gc.c (backptr_oflow): Static variable removed.
(freshq_head, freshq_tail, partial_gc_count): Static variables removed.
(freshq): Array renamed to freshobj.
(full): Variable renamed to full_gc.
(freshobj_idx): New varaible.

(make_obj): Add newly born objects to freshobj array rather than
freshq. If freshobj array is full on entry to this function,
trigger gc to empty it. make_obj no longer updates the free_tail;
the gc routine takes care of restoring this invariant.
(mark_obj): Follows rename of full_gc. Some code was not wrapped
in #if CONFIG_GEN_GC.
(mark, sweep_one): Follow rename of full_gc.
(sweep): On entry, restore free_tail invariant in the empty
free_list case. Code which processes freshq from tail to head
replaced by simple array walk of freshobj. Code wrapped properly
in #if CONFIG_GEN_GC.
(gc): Logic for triggering full gc simplified.
Check added for situations when a partial gc is called when
the free list empties, and it doesn't liberate enough memory.
This prevents the situation of partial gc being called over and over
again by make_obj, squeezing less and less memory each time until
finally it returns 0 objects, and more() is called.
(gc_is_reachable): Follows rename of full_gc, and #if CONFIG_GEN_GC
added.
(gc_set, gc_mutated): Simplified. Check if the backptr array
is full and trigger gc if so to flush it, then just add to the array.
