	(pv_set_to_unknown, pv_set_to_constant, pv_set_to_register,
	pv_constant_last, pv_add, pv_add_constant, pv_subtract,
	pv_logical_and, pv_is_identical, pv_is_register, pv_is_array_ref,

	Break out the decoding of S/390 instructions into separate
	functions, to make it more legible, and easier to check
	against the spec.

	is_rx, is_rxe): New functions.

	op2_bras, op_l, op_la, op1_larl, op2_larl, op_lgr, op1_lghi,

	enums for opcode values.  (Is this an improvement?)
