Generational GC tweaks.
* gc.c (make_obj): If we have room in the freshobj array,
but are out of objects, then call more. Without this,
we don't take proper advantage of this nursing area.
(gc): Set the full_gc flag after doing gc, in preparation
for next time. If we know full GC is coming, we can
adjust some behaviors. Increase the threshold for calling the more()
function to be the same as in the non-generational case:
less than 3/4 of the size of a heap scavenged.
(gc_set): Now does nothing if it is known that
a full gc is coming. Also, in the checkobj array overflow
case when we invoke gc, there is no point in adding obj
to the array, since it must have been promoted to the mature
generation.
(gc_mutated): Don't bother storing the object in the
array if a full GC is coming.
