Convert handle_tpi() to new guest access functions. The code now sets up a structure which is copied with a single call to guest space instead of issuing several separate guest access calls. This is necessary since the to be copied data may cross a page boundary. If a protection exception happens while accessing any of the pages, the instruction is suppressed and may not have modified any memory contents.
