	* call:16
		* In some circumstances we can move instructions

		This is only done if the resulting code is no larger

	* jmp:32 -> jmp:16					   2 bytes
	* jmp:16 -> bra:8					   1 byte

		* If the previous instruction is a conditional branch
		around the jump/bra, we may be able to reverse its condition
		and change its target to the jump's target.  The jump/bra
		can then be deleted.				   2 bytes

	* mov abs32 -> mov abs16				   1 or 2 bytes

	* Most instructions which accept imm32 can relax to imm16  1 or 2 bytes
	- Most instructions which accept imm16 can relax to imm8   1 or 2 bytes

	* Most instructions which accept d32 can relax to d16	   1 or 2 bytes
