  -----------
  [ValueTracking] Remove handling of KnownBits assumptions with invert

For all practical purposes, we only care about comparisons with
constant RHS in this code. In that case, an invert will be
canonicalized into the constant and it will be handled by other cases.

Given the complete lack of test coverage, I'm removing this code.
