Matt Pharr	83e1630fbc	Add support for fast division of varying int values by small constants. ... For varying int8/16/32 types, divides by small constants can be implemented efficiently through multiplies and shifts with integer types of twice the bit-width; this commit adds this optimization. (Implementation is based on Halide.)	2013-07-23 16:49:56 -07:00
