i386.c (ix86_builtins): New array for ix86 builtin function decls.

2006-11-18  Richard Guenther  <rguenther@suse.de>

	* config/i386/i386.c (ix86_builtins): New array for ix86
	builtin function decls.
	(def_builtin): New function.
	(def_builtin_const): Likewise.
	(ix86_init_mmx_sse_builtins): Mark sqrt and cvt builtins const.
