SPR_CMPEXCH_VALUE should be present in your cpu structure, should be a TCGv
like all of your other registers, and this expands to a simple move.

You will probably need to dispatch on the SPR number.  Some of these will be
normal moves to special register slots.  Some of these may require a function
call in order to handle the side effects.
