About 40% faster than the SSE2 implementation.
May not be required in future but good for reference.

- RGBA8 (DX9/OGL): 10x speed up on Radeon 5450, 2x speed up on other cards due to swizzle registers.
- RGB565: 2-3x speed up on all hardware
- Removed OpenCL compiler warnings (eg. redefine).
OpenCL is now optimally complete for DX9/OGL. The code is very fast on all supported hardware. No more updates are needed unless the spec changes or drivers improve. When I started, the OpenCL code was as slow or slower than CPU. Now, using the lowest end radeon that supports the code: a Radeon 45xx mobility, I experience a substantial 2-10x speedup over CPU. The benefits are more pronounced with modern hardware. A Radeon 5870 runs this code 20x faster than a 4550. Even ignoring speedups, the code benefits users by not using CPU for intermittent texture loads (unless GPU is your bottleneck). Instead, the CPU is able to do more important tasks.

Changes:
- IA4: 2x Speed up for all hardware and ATI glitch fixed (blocky text)
- IA8: 2x Speed up for all hardware
- New DX11 OCL Textures: I4, I8, IA4, IA8

Changes:
- Strict casting as required by NVidia. Now NVidia cards should work.
- Fixed Alpha CMPR bug.
Please tell me if you find any bugs. Current known bug is the 'Press' texture in Paper Mario that is meant to flash rainbow colours appears black. Other than that, everything should work on every videocard.

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.
