* 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. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5541 8ced0084-cf51-0410-be5f-012b33b47a6e
