* 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

* 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.

ESI is not available as callee save register on linux 64, so use R12, which
is available on windows 64, too. The only callee save register still available on
all platforms is EBP, but i guess we don't want to fiddle with that one.

* 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

call it for every instruction, like in DSPInterpreter::Step. Fix the analysis lookups
for DSP_IDLE_SKIP and DSP_LOOP_END.
After this patch, the block_size and the return value from the block always match,
except when an internal exception is detected. This will change in a later patch,
so we actually get some benefits from checking if we need to call HandleLoop().

It is pure luck that we did get a fresh (thus zeroed) memory area when not putting DSPLLE on thread. ClearIRAM() is supposed to only clear the non-static part.

The block_size seems to be not reliable, even after trying to more closely match
the interpreter by looking at the analysis for (addr+opcode->size-1) for detecting
the end of the block.
Since we need to "calculate" this number shortly before returning to
RunForCycles, it seemed logical to use the (up to now) unused return value
of the blocks.
Improves SMG2 here.

This is the safe variant that does not assume other
functions use R11 for &g_dsp.r, which they actually do.
So there is a lot unnecessary reloading of the register
getting emitted.
There are a few small changes exploiting pointers known
at emission time and making use of MComplex math.
Also renames m_LLEplaying to m_AIplaying in Core/AudioCommon.

Add some useful checking to J_CC/SetJumpTarget.
Refactor increment/decrement and reuse code with increase/decrease.

* Restore Audio Throttle to function properly, broken by Ayuanx many hundreds of revisions back.
* Simplify DSPLLE JIT dispatcher in preparation for an asm rewrite
* Remove hack that made DSPLLE JIT seem faster than it was by running fewer cycles, but resulting in bad sound. This shows off how mysteriously slow it is - I don't understand why it's not faster. Use the DSPLLE interpreter for now if you want to use DSPLLE.
* Made "DSPLLE on Thread" work properly with correct-ish timing - although the speed benefit is really small now.
If it seems like this change slows anything non-LLE down, try turning off Audio Throttle and use the frame limiter in options instead.

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

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
