Implemented most of the atomic operation support instructions

LoadPLocked
StorePLocked
StoreLConditional
StoreIConditional
CompareAndSwapI
CompareAndSwapL
CompareAndSwapP
CompareAndSwapN

n.b. loadPLocked/StorePLocked have been implemented directly using
independent ldaxr and stlxr calls. There is no Load{IL}Locked as the
Ideal code expects Store{IL}Conditional to behave as compare and swap
operations so they each use a ldaxr/stlxr pair
