util: import public domain code for integer division by a constant
Compilers can use this to generate optimal code for integer division
by a constant.
Additionally, an unsigned division by a uniform that is constant but not
known at compile time can still be optimized by passing 2-4 division
factors to the shader as uniforms and executing one of the fast_udiv*
variants. The signed division algorithm doesn't have this capability.
