* ggc.h (struct alloc_zone): Move forward declaration up.
(new_ggc_zone): New function prototype.
(destroy_ggc_zone): Ditto.
* ggc-simple.c (new_ggc_zone): New function, does nothing.
(destroy_ggc_zone): Ditto.
* ggc-page.c (new_ggc_zone): New function, does nothing.
(destroy_ggc_zone): Ditto.
* ggc-zone.c (struct page_entry): Fix comment.
(ggc_alloc_typed): Use a switch statement instead of ifs.
(new_ggc_zone): New function to set up a new GC zone.
(destroy_ggc_zone): New function to remove a GC zone.
init_ggc): Use new_ggc_zone to set up the default zones.
(ggc_collect): Walk a list of zones, instead of just the
default zones. Report statistics using the zone name.
