2a0f750a83 Optimize memory accesses on little endian systems that can do unaligned 
accesses to memory. Fix build when vm.hpp is included in a C program.

1dbe1179c6 Merge in "keycodes" support from Basilisk II. e.g. make French keyboard 
layout work correctly for me.

e9f3546539 Remove even more obsolete code. Drop TBL/TBU registers, they are manually 
handled through the mftb instruction accessor.

cf0ed72f24 Remove obsolete code related to PPC_NO_FPSCR_UPDATE, PPC_LAZY_PC_UPDATE, 
PPC_LAZY_CC_UPDATE, PPC_HAVE_SPLIT_CR defines.

b66d8ef433 Fix "ignoresegv" case to actually skip the faulty instruction. Merge 
conditions to skip instruction on SIGSEGVfrom PowerPC native mode. The
instruction skipper takes care to set the output register to 0.

0260210ddf - XLM_IRQ_NEST is always in native byte order format since any write to 
this variable go through {Enable,Disable}Interrupt().
- Add Ether thunks but only for WORDS_BIGENDIAN case since we do need more
complicated translation functions.

cd86ff9e94 - Start emulating the FPSCR. Fix mtfsf, mffs. 
- Implement mftbr so that MacOS can fully boot with extensions. However,
  using clock() is probably not the right solution. Patching UpTime from
  DriverServicesLib et al. may be a better solution.

aebcb7a6bb New testing framework faster to compile and more flexible. i.e. we now 
generate 350K+ instructions. This exhausts errors for mullwo & divw.

30bd089279 PowerPC floating-point registers are now an union of uint64 & double. This 
eases FP load/stores.

a42281aad1 Implement partial block cache invalidation. Rewrite core cached blocks 
execution loop with a Duff's device. Gather some predecode time statistics.
This shows that only around 2% of total emulation time is spent for
predecoding the instructions.

f0ea192460 Optimized pointers to non virtual member functions. This reduces space 
and overhead since runtime checks are eliminated. Actually, it yields
up to 10% performance improvement with specialized decoders.

89d0f9ca29 Integrate spcflags handling code to kpx_cpu core. We can also remove 
oldish EXEC_RETURN handling with a throw/catch mechanism since we
do have a dependency on extra conditions (invalidated cache) that
prevents fast execution loops.

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

1b9876889e - Record address range of block to invalidate. i.e. icbi records ranges 
and isync actually invalidate caches

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
