	* call:32 -> calls:32					   1 byte
	* call:16 -> calls:16					   1 byte
		* These are done anytime using "calls" would result
		in smaller code, or when necessary to preserve the
		meaning of the program.

	* call:32						   varies
	* call:16
		* In some circumstances we can move instructions
		from a function prologue into a "call" instruction.
		This is only done if the resulting code is no larger
		than the original code.

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

	We don't handle imm16->imm8 or d16->d8 as they're very rare
	and somewhat more difficult to support.  */
