	(ix86_builtin_type_tab, ix86_get_builtin_type): New.
	(ix86_builtin_func_type_tab, ix86_get_builtin_func_type): New.
	(struct builtin_isa): Remove GTY marker.  Replace tree type with
	ix86_builtin_func_type; add set_and_not_built_p.
	(def_builtin): Change type parameter to tcode; use
	ix86_get_builtin_func_type; update all callers.  Accept zero mask
	to mean the builtin is unconditionally available.
	(ix86_add_new_builtins): Use set_and_not_built_p instead of type
	being set to NULL.
	(enum ix86_special_builtin_type, enum ix86_builtin_type): Remove.
	Update some users to rationalized enumeration codes from new include.
	(enum multi_arg_type): Remove.  Replace all enumeration values
	with defines to new ix86_builtin_func_type.
	(ix86_init_mmx_sse_builtins): Don't build any types here.  Defer
	all type resolution to def_builtin.
	(ix86_init_builtin_types): Split out from ...
	(ix86_init_builtins): ... here.  Use ix86_get_builtin_func_type.
