~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: 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.
