pierre 98752f2a1e Core/DSPCore: Changed g_dsp._r back to g_dsp.r. Removed the check*Exclude 
functions accidentally added. Fixed the jitted ar register arithmetic.
Added a CMakeList.txt for the UnitTests, but did not add the subdirectory
to Source/CMakeLists.txt.

pierre fc1db5eaa0 Core/DSPCore: Reorganize register layout for accessing accumulators 
(acc and ax) and product register with one read/write.

Gives a minuscule speedup of not more than 4%. In exchange, breaks all
your out-of-tree changes to dsp. Tests are not building again, yet.

pierre 4b9831cdce Core/DSPCore: Extended opcode handling fixes 
* Make writeToBackLog private to DSPIntExtOps.cpp 
  (JIT variants of 'l and 'ln are disabled and broken as is)
* Make zeroing of the backlog conditional on doing an interpreter fallback and
  do it at a few more places
* Fix selection of cleanup for extended opcodes.
* Fix the DSP unit tests to correctly emit the function prolog/epilog
  (else EBX wouldn't be saved)
* Add a few more DSP unit tests

Marko Pusljar d1f0294053 DSPLLE + 2 small fixes, many GC AX games are almost perfect (sound wise, ex. Super Monkey Ball 1/2), if PC is fast enough (3GHz C2D+), Zelda type games too slow to be testable

nakeee b787f5f8f7 DSPLLE: attempt to fix extended ops please review this patch carefully. 
thinks to note
- All ext commands should call zeroWriteBackLog() (before changing any 
reg)
- increase/decrease ar functions now only return a value not actually 
change anything
