[Based on work by Jim Blandy]

	* gdbtypes.h (builtin_type_v16qi, builtin_type_v8hi): Export.
	(builtin_type_vec128): Export.

	* gdbtypes.c (builtin_type_v16qi, builtin_type_v8hi): New SIMD
	types.
	(builtin_type_vec128): New builtin type for 128 bit vector
	registers.
	(build_gdbtypes): Initialize builtin_type_v16qi and
	builtin_type_v8hi. Create the vec128 register builtin type
	structure.
	(build_builtin_type_vec128): New function.
 	(_initialize_gdbtypes): Register builtin_type_v16qi and
	builtin_type_v8hi with gdbarch. Same for builtin_type_vec128.

	* rs6000-tdep.c (rs6000_register_virtual_type): Change type of
	AltiVec register to new builtin type.
