pierre c33f46406e Core/DSPCore: Improve Interpreter address register add/sub, convert to
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)
