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)

* Completed the JIT versions of the DSP Multiplier instructions (5 instructions added).
* Bug fixed the dec and lsr16 instructions.
* Minor code clean-up.

* Completed the JIT versions of the DSP arithmetic instructions (28 instructions added).
* Added JIT versions of maddx and msubx (thanks to LM1234).
x64 only

* Added 21 Arithmetic instructions to the JIT
* Used the DSPAnalyser to identify arithmetic/multiplier instructions that precede a conditional branch. This allows the JIT to skip updating the SR when nothing would read from it. Marked all arithmetic/multiplier instructions in the DSPTable for this purpose.
* Converted CheckExternalInterrupt into ASM
* Fixed a couple instructions in DSP Load/Store

* Added jit versions of 5 DSP LoadStore instructions: srs, lrs, lr, sr, si
* Renamed MainOpFallback to Default for consistency in naming with JIT64
* Made ext_dmem_read and ext_dmem_write more generic for wider use
* Optimised dmem_read and dmem_write slightly
* Added dmem_read_imm and dmem_write_imm optimised versions
git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6596 8ced0084-cf51-0410-be5f-012b33b47a6e
* Optimised the updating of g_dsp.pc in the compile loop (code by kiesel-stein)
* Added JIT version of LRI (code by kiesel-stein)
* Added JIT versions of the branch instructions (code by Jack Frost)
* DSP_SendAIBuffer fix (code by Mylek)
* Marked instructions that update g_dsp.pc in the DSP table and updated PC based on the table (speed up)
* Fixed the signed bits not being set properly in the addr instruction
* Created a MainOpFallback function to use interpreted versions of the instructions if necessary (code by kiesel-stein)
* Disabled the jit versions of subarn and addarn as they are slowing down NSMBW
The above work in both x86 and x64 modes.

Also add the mask for ADPCM predictor, like r6480 does.
Tested 64 bit linux/windows. At least compiles for 32 bit windows, but
with these binaries most of my guest software fails with
DSPLLE(interpreted and jit) when it gets to do actual work.

void pushExtValueFromReg(u16 dreg, u16 sreg);
void popExtValueToReg();
instead of the backlog.
Someone might want to add it to the Unit test

And to help test things like that: DSPJitTester (use with caution on x64, most likely fails there; r5250 might be why)

enabled nr in jit after getting skid_au's help in writing the inscrease_addr_reg.
ector can you please take a look and see if the loop code makes sense? it seems
no one it really sure how loops suppose to work in jit

functions are passed by value rather than by reference
This is part of a bigger change so please report if it broke compile

addis, cmpis, xori operate on ACx.M instead of ACCx
addax, subax, movax use whole AXx reg, not just AXx.L
addpaxz uses whole AXx instead of AXx.H
git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@4817 8ced0084-cf51-0410-be5f-012b33b47a6e
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
