	* gdbarch.sh (register_type): New function with predicate.
	(REGISTER_VIRTUAL_TYPE): Change to function with predicate.
	* gdbarch.h, gdbarch.c: Re-generate.
	* arch-utils.c (generic_register_byte): Use generic_register_size.
	(generic_register_size): When available, use
	gdbarch_register_type.
	* regcache.c (init_regcache_descr): When available, initialize the
	register type array using gdbarch_register_type.  If the
	architecture supplies gdbarch_register_type, do not use the legacy
	regcache layout.
	* d10v-tdep.c (d10v_register_type): Replace
	d10v_register_virtual_type.
	(d10v_gdbarch_init): Set register_type instead of
	register_virtual_type.
