Summary
REGRESSION: Apparent hang of PCE.js Mac OS System 7.0.1 on ARM64 devices

This is fundamentally an 68K instruction emulator. Tracked the issue to MacroAssemblerARM64.h where we inadvertently use the destination register for both the source and destination in two arg or64(), eor32( ) and eor64().

I think so. I'll spend some time to see if I can come up with one.
