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.

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.
