ggc-none.c, [...] (ggc_alloc_obj): Rename it ggc_alloc, drop second argument, never clear returned memory.

toplevel:
	* ggc-none.c, ggc-simple.c, ggc-page.c (ggc_alloc_obj): Rename
	it ggc_alloc, drop second argument, never clear returned memory.
	* ggc-common.c (ggc_alloc_string): Use ggc_alloc.
	(ggc_alloc_cleared): New.
	* ggc.h: Prototype ggc_alloc and ggc_alloc_cleared, not
	ggc_alloc_obj.  Remove ggc_alloc macro.
	(ggc_alloc_rtx, ggc_alloc_rtvec, ggc_alloc_tree): Use ggc_alloc.

	* rtl.c (rtvec_alloc): Clear the vector always.
	(rtx_alloc): Clear the first word always.  Remove dirty
	obstack tricks (this routine is no longer a bottleneck).
	* tree.c (make_node): Clear the new node always.
	(make_tree_vec): Likewise.
	(tree_cons): Clear the common structure always.
	(build1): Likewise; also, clear TREE_COMPLEXITY.
	* gengenrtl.c: Use puts wherever possible.  Remove extra
	newlines.
	(gendef): Clear the first word of an RTX in the generator
	function, irrespective of ggc_p.  Initialize '0' slots to
	NULL.
	(genlegend): Don't generate obstack_alloc_rtx routine, just a
	thin wrapper macro around obstack_alloc.

	* stmt.c (expand_fixup): Use ggc_alloc.
	* c-typeck.c (add_pending_init): Use ggc_alloc.
	* emit-rtl.c (init_emit_once): Clear CONST_DOUBLE_CHAIN(tem).
	* varasm.c (immed_double_const): Set CONST_DOUBLE_MEM(r) to
	const0_rtx when it is created.
	(immed_real_const_1): Set CONST_DOUBLE_CHAIN(r) to NULL_RTX if
	we are not in a function.

	* tree.c (tree_class_check_failed): Make second arg an int.
	* tree.h: Update prototype.

cp:
	* call.c (add_candidate): Use ggc_alloc_cleared.
	* decl.c (lookup_label): Likewise.
	* lex.c (retrofit_lang_decl): Likewise.
