Noah Goldstein 7c96469ea8 [ValueTracking] Extend LHS/RHS with matching operand to work without constants. 
Previously we only handled the `L0 == R0` case if both `L1` and `R1`
where constant.

We can get more out of the analysis using general constant ranges
instead.

For example, `X u> Y` implies `X != 0`.

In general, any strict comparison on `X` implies that `X` is not equal
to the boundary value for the sign and constant ranges with/without
sign bits can be useful in deducing implications.

Closes #85557
