james.jdunne de40765504 Quick fix for DataReadU32xN_SSSE3. Should fix crashes caused by r6802.

james.jdunne b6a1e9376f 45% speed improvement in RGBA -> BGRA conversion over reference C code. This might turn out to be unnecessary once I refactor the CreateTexture2D/ReplaceTexture2D to call the texture decoder instead of vice-versa and have the SSE2 code convert directly to BGRA and write directly to the D3D allocated texture. 
Need to investigate source texture alignment and where to introduce that, if it is possible.

james.jdunne 1671917472 Missed one MSVC-ism. Should fix build for Linux. Last revision should still work for Windows. No functionality changes this time.

james.jdunne 2841d67ce3 Faster SSE2 optimized GX_TF_CMPR texture decoder which gets ~40% speed improvement on x64 and ~50% improvement on x86 as compared to reference C code. 
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.

james.jdunne 5ca3adde3c Enabled SSE2 optimization of GX_TF_CMPR decoder only for x86 builds. It can't compete with the x64 optimized reference C code.

james.jdunne 0b46610d49 Changed order of operations in Profiler.cpp to calculate non-zero values for 'cost'. Integer division was too early. Credit to my brother, Joe, for figuring this one out.

james.jdunne 6eff71b893 Fixed S3TC DXT1 decoder implementation. I see ~40% speed improvements running on x86 Intel hardware and 0% improvements running on x64 AMD hardware. Strange. More investigation to follow!

james.jdunne 7703018632 Possibly fixed game crash issues by switching to unaligned SSE2 loads/stores.

james.jdunne d4ced9e995 Patch applied from issue 3829, author [email protected]. 
Tweaked SetMultiVSConstant functions to prefer glProgramEnvParameters4fvEXT over glProgramEnvParameter4fvARB with fall-back for older harder.

james.jdunne 134fca9b82 ~68% increase in GX_TF_IA8 decoding speed. Not an oft-used texture format. An example use is the Wii cursor in MKWii in the menus.

james.jdunne 343e3f7c75 ~80% speed improvement in decoding GX_TF_I8 textures. Yes, EIGHTY PERCENT. However, for MKWii movie playback I still can't break the fluffin' 48 FPS boundary on my machine! There's something else at play here because this decoder is ridonkulously fast. 
~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.

james.jdunne b038df64bf TextureDecoder.cpp: new SSE2 optimized GX_TF_I8 decoder. Probably not ultimately optimal SSE2 code, but provably better (on my machine) than the memset version. Tested with __rdtsc counts in an independent project. I get about 6-7 FPS more on average during the intro movie playback in Mario Kart Wii. Hope this compiles for GCC okay. 
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.
