SWP Instruction no more ARMv8

With the SWP ARM Instruction no more - on the ARMv8 - it would be nice 
if someone could come up with a replacement.

DivEmulator module (Adrian Lees) comes up with a method of catching 
the error - module looks expandable.

A means of implementing SWP in the remaining instruction needs to be 
devised - plus a means of testing it.

SWP :- This instruction swaps a word (or byte) in memory for a word 
(or byte) in a register.
