There's nothing inherently fixed-width in the code. All that's required to generalize it is to make everything internally 64-bit and pass UINT_BITS in as a parameter to util_compute_fast_[us]div_info. With that, it can now handle 8, 16, 32, and 64-bit integer division by a constant. We also add support for division by 1 and by other powers of 2. This is useful if you want to divide by a uniform value in a shader where you have the opportunity to adjust the uniform on the CPU before passing it in.
