ggc-zone.c: New file, zone allocating collector.

2003-10-26  Daniel Berlin  <dberlin@dberlin.org>

	* ggc-zone.c:  New file, zone allocating collector.
	* configure: Accept zone option for --with-gc
	* configure.in: Ditto.
	* ggc.h (ggc_pch_count_object): Pass bool indicating
	stringiness. Update all callers.
	(ggc_pch_alloc_object): Ditto.
	(ggc_pch_write_object): Ditto.
	(ggc_alloc_rtx): Use typed allocation, since all RTX's are of a single
	type.
	(ggc_alloc_rtvec): Ditto.
	(ggc_alloc_tree): Use zone allocation, since some things using this macro
	aren't a single typecode.
	* ggc-none.c (ggc_alloc_typed): New function.
	(ggc_alloc_zone): Ditto.
	* ggc-page.c: Ditto on both functions.
