Log message:
	* fold-const.c (fold): An equality comparison of a non-weak object
	against zero has a known result.  Similarly an equality comparison
	of the address of two non-weak, unaliased symbols has a known result.
	
	* ggc-page.c (struct page_entry): New field PREV.
	(ggc_alloc): Update PREV field appropriately.
	(sweep_pages): Likewise.
	(ggc_free): Likewise.  Use PREV field rather than loop to
	improve ggc_free performance.
	
	cp/
	* init.c (build_vec_delete_1): Convert 2nd argument to NE_EXPR to
	the proper type.
