d0a2277325 Gather stats about compile time. Define KPX_MAX_CPUS to 1 for allowing 
allocation of translation cache into .data section on PowerPC.

aee3e05e4b The JIT should work now but there is an extra bottleneck causing it to 
not match Kheperix speeds while executing Linux/ppc binaries.

Fix x86 DYNGEN_OP_FLAGS settings. Only allocate translation cache in .data
on PPC since x86 can do jumps anywhere.

73d51962f6 Merge in-progress PowerPC "JIT1" engine for AMD64, IA-32, PPC. 
The merge probably got wrong as there are some problems probably due to the
experiment begining with CR deferred evaluation. With nbench/ppc, performance
improvement was around 2x. With nbench on x86, performance improvement was
around 4x on average.

Incompatible change: instr_info_t has a new field in the middle. But since
insertion of PPC_I(XXX) identifiers is auto-generated, there is no problem.

7968a20100 Handle "JIT1" engine but disable it for now since there are some problems 
with SheepShaver integration from Kheperix.

10c04e2654 Enable possibility to manually pass VM_MAP_32BIT & friends. This is needed 
for the PowerPC "JIT1" engine.

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.

30bd089279 PowerPC floating-point registers are now an union of uint64 & double. This

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.
