  [Attributor][FIX] AAValueConstantRange should not loop unconstrained

The old method to avoid unconstrained expansion of the constant range in
a loop did not work as soon as there were multiple instructions in
between the phi and its input. We now take a generic approach and limit
the number of updates as a fallback. The old method is kept as it
catches "the common case" early.
