Jason Ekstrand 74492ebad9 nir: Add a pass for lowering integer division by constants 
It's a reasonably well-known fact in the world of compilers that integer
divisions by constants can be replaced by a multiply, an add, and some
shifts.  This commit adds such an optimization to NIR for easiest case
of udiv.  Other division operations will be added in following commits.
In order to provide some additional driver control, the pass takes a
minimum bit size to optimize.
