Haicheng Wu d60ae33d29 [CVP] Convert an SDiv to a UDiv if both operands are known to be nonnegative 
The motivating example is this

for (j = n; j > 1; j = i) {
   i = j / 2;
}

The signed division is safely to be changed to an unsigned division (j is known
to be larger than 1 from the loop guard) and later turned into a single shift
without considering the sign bit.
