		and change its target to the jump's target.  The jump/bra
		can then be deleted.				   2 bytes

	* mov abs24 -> mov abs16	2 byte savings

	* Most instructions which accept imm24 can relax to imm16  2 bytes
	- Most instructions which accept imm16 can relax to imm8   1 byte

	* Most instructions which accept d24 can relax to d16	   2 bytes
	- Most instructions which accept d16 can relax to d8	   1 byte

	abs24, imm24, d24 all look the same at the reloc level.  It

	the various relaxable operand types.

	We don't handle imm16->imm8 or d16->d8 as they're very rare
