Matt Pharr 8bc7367109 Add foreach and foreach_tiled looping constructs
These make it easier to iterate over arbitrary amounts of data
elements; specifically, they automatically handle the "ragged
extra bits" that come up when the number of elements to be
processed isn't evenly divided by programCount.
