Common-opencl: Change an ambiguous function name.
Re-enable vector width 3. Most problems with it not working is because
our LWS/GWS enumerations pick unsuitable figures for that width.
OpenCL formats: Use shared functions.
RAKP: Use lower default KPC so weak devices don't die on us.
RAKP OpenCL tweaks.
Try to fix a regression on 13.4 Catalyst driver (revert performance to 13.1 situation).

common-opencl.c: Make it use its own helper functions w/ available,
plus a bunch of whitespace fixes.
RAKP OpenCL: Implement proper GWS tuning.
