pierre 47eb5c3416 Core/DSPCore: Only check for internal exceptions in DSPEmitter::checkException, but
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().

pierre e9d91fb9f3 Core/DSPCore: Initialise all of the code blocks
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.

pierre 34909ecebc Core/DSPCore: Make the JIT blocks return the number of cycles executed.
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.

pierre b80e207a8a Core/DSPCore: Make JIT work on 64 bit hosts
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.

j4ck.fr0st 89c4068663 Fix a bug in DSP Jit where branches had a blockSize of zero.
Add some useful checking to J_CC/SetJumpTarget.
Refactor increment/decrement and reuse code with increase/decrease.

hrydgard 1d1b08a091 Core audio system work (Watch for regressions please!):
* 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.

nakeee de081d0900 DSP jit: fixed some crash by pop/push (close to bhaal's solution)
If it breaks 64bit you know what to uncomment :-)

nakeee d86167961c DSP Jit enable ls* and sl* in jit.
Anyone feel like helping with the unit test?

nakeee 282cf6c6b5 DSP jit: 'mv 's 'sn are now jitted. Added
void pushExtValueFromReg(u16 dreg, u16 sreg);
	void popExtValueToReg();
instead of the backlog.
Someone might want to add it to the Unit test

flags such as S40 which we can use to optimize compile.

nakeee 91c6f5acba DSP Jit removed useless push/pop (at least I hope they were useless).
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
