pointer cannot be reached by 32bit displacement.
RAX is caller save and non-parameter in all 64 bit ABIs, so it should be safe
to clobber it on function call.

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.

This should eliminate the crackling with alsa and pulseaudio backends and replace it
with much nicer pauses. This is only interesting for audio backends that do not
respect Mixer::GetNumSamples() and should not impact users able to run the DSPLLE at
full speed.
The cost of this is an added LLE audio latency of about 0.06 s in the continuous
playback case. If that is too much, lower the low watermark.

If you see this alert, dolphin will probably crash in a few moments.
Found in the course of fiddling with DSPLLEs JIT, which puts its data
structures and static code somewhere above 0x7fff00000000 on my machine, making
it unreachable via 32bit displacements from the created code at ~ 0x40000000.
Fixed all the offending places in DSPLLEs JIT to emit register indirect accesses,
only to find out that the generated code is slower than the interpreter and does
work just as good(or bad). Oh well, back to DSPHLE it is then.

final rendering of (at least) Sonic Unleashed.
This should be (nearly) invisible in Z16 depth copies and in games, but there is
some chance that it collides with other such border cases. There probably is some
room to decrease the adjustment but 9999999/10000000 is not enough. A static offset
may be an option, too. I don't know if the game can/does set something like that.

eating each others events.
Manifests itself in GPU thread waiting forever for a reply in GL library code(and thus
a frozen emulation). Most of the time, this can be resolved by creating more events
(clicking, changing focus), but sometimes it stays stuck.

The theoretical result is slightly different to the original shader because the
final adjustment is to the range [0/255..255/255] instead of
[0/16777215..16777215/16777215].
The real result is vastly different on some gpus that were giving incorrect results
of bits 23..16 (y-component) wrapping around while bits 31..24 (z-component)
stayed the same, and bits 31..24 changing while in the middle of the value range
for bits 23..16 for large depth values.
This should fix issue #3123.

I am not sure i am understanding what the pipeline really does, and more so what
the GC/WII expects here. If my comments are incorrect, please let me know.
This was tested with MP2:E, ZWW on r6075.

glxMakeCurrent is supposed to error out when the context is
still current in another thread. NVIDIA handles that, but mesa3d errors.

All visuals with parameter GLX_SAMPLE_BUFFERS_ARB = 0 have
GLX_SAMPLES_ARB = 0, so the old code would only ever choose
visuals with GLX_SAMPLE_BUFFERS_ARB>=1 and GLX_SAMPLES_ARB>=1.
Some drivers do not export any multisampling capable visuals,
so dolphin fails to find a matching visual and falls back to
the single buffered visual(which does not work for some yet
unknown reason). Fixes issue #2647.

This should give the exact same shader code except for the cases of
SELA == SELB and SELC == 1, the latter only for the color combinder.
In these two cases the results of the shader should not change in any way.
It would have been possible to optimize the SELC == HALF case too, if
the actual factor had been 0.5f instead of 0.4980392f.

strcasecmp is provided by Source/Core/Common/Src/CommonFuncs.h

vsnwprintf, according to MSDN.

The real hardware probably always sends the result of its computations
to the alpha test/fog units, in parallel to its registers, but those
only take the result of the last texenv stage.
This makes grass show up in ZTP, where the last texenv stage oddly writes to
reg #3 instead of #0.

This removes some bad behaviour, like the audio thread busy waiting inside ALSA code,
missing begins of voice samples(due to DSP_HLE code not getting called often enough).
Turns out my understanding of ALSA API was lacking.
Tested with pulse plugin and directly on my intel-hda/realtek hardware.

The fix is asking alsa for a prefered "hardware" buffer size, so alsa does not fall
back to pulseaudios offering of ~1 minute. Additionally, alsa busy waits when pulseaudio
is used, sw:avail_min is set and hw:buffer_size is small.
