Second:
A experiment. implemented parallelization in texture decoding using openmp. is most a experiment to test the performance in different os/plataforms. in my system (windows x64 amd 1055t) give a speedup in large textures, but i tested in in intel dual core and gives a slowdown. o i limited the use for large textures and cpus with more than 3 cores.
please test an let me know if it improves or degrades the speed.
please for linux and osx user. to enable this you will have to enable your compiler support for openmp to test this code.

some code additions for future use ;).
please gcc user test this as i don't have opportunity to test it myself i only use reference code to.

This makes the OS X build more robust and should help pave the
way for the integration of the video plugins as well as LTO.
There are now no more global class level namespace conflicts left,
as evidenced by the fact that Dolphin can be linked with -all_load,
not that you would want to.

The code now uses direct pointer access from C code to write the colors to the destination texture instead of trying to force them back up into an __m128i and a single write call. This is what produces the major speed-up.

GX_TF_RGBA8 texture decoder optimized with SSE2 producing a ~68% speed increase over reference C implementation.
TABified the entire document per NeoBrainX. :)

~25% speed improvement in decoding GX_TF_RGB5A3 textures which aren't used very much. I thought it would help for movie playback but I misled myself. Video playback has nothing to do with this texture format.
Next I'll see if I can knock out some of these other texture decoders. Byte swizzling I'm sure can somehow be accomplished using _mm_unpacklo_epi8 trickery, so that'd be another big win I hope.

TextureDecoder.cpp: merged two functionally identical decode5A3RGBA and decode5A3rgba methods.
OpcodeDecoding.cpp and DLCache.cpp: optimization for GX_LOAD_XF_REG. The PSUHFB solution sounds better for SSSE3, but this is a small win for the default case.

use plain vertex arrays instead of VBOs to render in Opengl plugin as the nature of the data make VBOs slower. This must bring, depending on the implementation, a good speedup in opengl.
in my system now opengl and d3d9 have a difference of 1 to 5 fps depending of the game.
some cleanup and a little work pointing to future improvements in the way of rendering.
please test and check for any errors.

The GCC model for extended instructions like these is that you compile
with -msse3 etc. These affect code generation for whole compilation units,
so the idea is that you have a separate .c file for each instruction set
class and then indirect to the desired one at runtime.
Without e.g. -msse4.1, the GCC built-ins used by <foointrin.h> are not
available. However, in our specific case of compiling with -msse2 and
wanting to use SSE3.1 code, enough built-ins are available that we only
need to provide a little hack for pshufb.
Upgrading this to also use SSE4.1 instructions doesn't appear feasible
without a lot of undesirable duplication of GCC built-in functions and
headers, so we'd probably have to move to the GCC model of separate
source files for that.

Fix the decoder codepath when OpenCL is enabled and the DX11 plugin is used.
Added the DX11 plugin to the Dolphin project dependencies.
