Applied the logic from r6691 to the LLE dec/add/sub functions so they work without ToMask. This should give a modest speedup for these.
Pierre's AR inc was already perfect and I only adjusted its logic a bit for visual consistency between the interpreter and JIT code.
Also applied Pierre's optimization from the LLE inc to the Int inc.

Adjusted the code work without ToMask.
This code should be functionally identical for all inputs to the previous code.

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.

(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.

assembler for JIT. Replace JIT ToMask() with a different variant. Remove
superfluous zeroWriteBackLog calls(added by me).
Core/Common: Don't bother creating a string and calling into a Logs trigger()
when there is noone listening. Change AtomicLoadAcquire for gcc to just
make the compiler not reorder memory accesses around it instead of doing
a full memory barrier, per the comment in the win32 variant.
Core/AudioCommon: Fix a use of uninitialized variable inside libalsa.
Microbenchmarking results for ToMask variants:(1 000 000 000 iterations):
cpu\variant| shifts | bit scan
intel mobile C2D@2.5GHz | 5.5s | 4.0s
amd athlon64x2@3GHz | 6.1s | 6.4s
(including some constant overhead identical to both variants)

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
