564c43c907 Remove ppc_cur_instruction global variable 
Replace it wth an explicit opcode parameter that is passed around. That
is both slightly easier to reason about (to trace where it comes from)
and slightly faster, since it can be read from a register.

On my machine takes booting to "Welcome to Macintosh" being output in
a verbose boot of Mac OS X 10.2.8 from 31.8s to 30.6s (average of 5
runs, measured using deterministic mode and looking at when execution
reaches PC 0x90004a88).

461d859e73 ppcmmu: add debug memory reading function. 
This function saves and restores the MMU state
so no invalid user input can break CPU execution.
