9ce43c6cf3 Fix ASYNC_IRQ build but locks may still happen. Note that with a predecode 
cache, checking for pending interrupts may not be the bottle neck nowadays.

60d34a6816 Rewrite interrupts handling code so that the emulator can work with a 
predecode cache. This implies to run in interpreted mode only while
processing EmulOps or other native (nested) runs.

Note that the FLIGHT_RECORDER with a predecode cache gets slower than
without caching at all.

d766049d59 - enable multicore cpu emulation with ASYNC_IRQ 
- move atomic_* operations to main_unix so that they could use spinlocks or
  other platform-specific locking mechanisms

ebb67f0421 - 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.

1012da75dd - Cleanups & make sure PPC emulator config is setup in sysdeps.h 
- Log r24 in SheepShaver mode as this represents the 68k emulator PC

b8b139faf2 - Share EmulatorData & KernelData struct definitions 
- Introduce new SheepShaver data area for alternate stacks, thunks, etc.
- Experimental asynchronous interrupts handling. This improves performance
  by 30% but some (rare) lockups may occur. To be debugged!

3851071ecd Try to handle XLM_IRQ_NEST atomically in emulated PPC views. Fix placement 
of fake SCSIGlobals (disabled for now). Switch back to mono core emulation
until things are debugged enough. Implement get_resource() et al.
