Hi! This is my first commit so be nice :) 

New OpenCL updates:
 - OpenCL bug with ATI SDK (GPU or CPU) fixed.
 - IA4 texture loop unrolled. 12x speed up on 4xxx series.
 - Completed rewriting RGB5A3 texture decode. 20% faster.
 - Redundant code removed from CMPR and RGB5A3 (Alpha, shift).
 - Made use of optimised OpenCL functions (upsample, bitselect).
 - Cleaner code.

Tested and working with DX9 plugin. DX11 plugin will NOT work due to a recent commit affecting VideoCommon. You can use this file with an older DX11 plugin (~r5730), however.
