radeonsi: use faster integer division for instance divisors
We know the divisors when we upload them, so instead we can precompute
and upload division factors derived from each divisor.
This fast division consists of add, mul_hi, and two shifts,
and we have to load 4 dwords intead of 1.
This probably won't affect any apps.
