gc: small memory support.
* configure (small_mem): New variable. Provide help text and
show default value of --small-mem option. Generate
CONFIG_SMALL_MEM in config.h.
* gc.c (HEAP_SIZE, CHECKOBJ_VEC_SIZE, MUTOBJ_VEC_SIZE,
FULL_GC_INTERVAL, FRESHOBJ_VEC_SIZE, DFL_MALLOC_DELTA_THRESH):
Define conservative values of these constants if
CONFIG_SMALL_MEM is in effect.
