PowerPC: Explicitly savestate PowerPCState members

Browse Source 
Makes it more obvious which data is going into the savestate.
It also allows PowerPCState and InstructionCache to potentially
contain members that don't necessarily need to be saved to the save state.

It also gets rid of any potential padding data being put into the save
state.
