[llvm-branch-commits] [mlir] [mlir][Interfaces][NFC] `ValueBoundsConstraintSet`: Delete dead code (PR #86098)

[Matthias Springer via llvm-branch-commits]

There is an assertion that the stop condition is not satisfied for the the starting point at the beginning of `computeBound`. Therefore, that case does not have to be handled later on in that function.
