- Minor optimization to execute_ppc() as we apparently don't need to move
...
target PC into CTR.
- Fix breakage introduced during little endian fixing. We now assume that
MacOS doesn't rely on any PPC register that may have been saved on top
of it stack. i.e. register state is saved onto native stack.
