1. Set valid ref range when regexp is matched …

   Last match global variables are set when the regexp is matched, not when
   it's defined. This meant that the previous implementation gave incorrect
   results when those things happened separately, e.g. when a regexp was
   assigned to a local variable or a constant and then matched elsewhere.
   
   This change means that the cop only handles matching on regexp literals,
   but that was the only case where it worked correctly before anyway. It
   should be possible to improve the cop to handle more complex cases with
   `VariableForce`, but that can be done as a separate change.
