[InstCombine] Fold an unsigned comparison of `add nsw X, C` with a constant into a signed comparison (#103480)
Given an unsigned integer comparison of `add nsw X, C1` with some
constant `C2` we can fold it into a signed comparison of `X` and `C2 -
C1` under the following conditions:
* There's a `nsw` flag on the addition
* `C2` is non-negative
* `X + C1` is non-negative
* `C2 - C1` is non-negative
