[ValueTracking] Use `KnownBits::sdiv` for `sdiv` opcode in `computeKnownBits`
We now of an implementation of `KnownBits::sdiv` so we can implement
this case.

[ValueTracking] Pass `exact` flag to `KnownBits::udiv` in `computeKnownBits`
This information was previously missing but we can use it for
determining the low-bits.

[KnownBits] Improve `KnownBits::udiv`
We can more precisely determine the upper bits doing `MaxNum /
MinDenum` as opposed to only using the MSB.
As well, if the `exact` flag is set, we can sometime
