Adding basic constant checks and updates to memory instructions. 

Only those instructions likely to have immediate values have been updated.
It'd be nice to go further than this and a) centralize the ea calculations
b) move this all to the analysis pass c) generate mov's in Read/WriteMemory
using the immediates as bases instead of all the register work.

Also fixing a broken stwcx that was causing crashes.
