Generic CPU and GPU loops with tiled iteration

[datnamer]

@tim.holy

GPU kernels explicitly looping over blocks of pixels. If you do the typical one-output-pixel-per-thread then it may not be relevant.

TiledIteration’s main advantage is in reusing cache, “ha

I don’t mean images necessarily, but any generic looping operation like matrix multiply or sum. Or do you mean a pixel more generically.
