	rather than a constant that is 2**X.  Reorder them to put bits for
	operands that have symbolic names in the upper bits, so they can
	be packed into an int where the lower bits contain the value that

	that the opcode can have two vector instructions in a single
	32 bit word and we have to encode/decode both.
