  Log Message:
  -----------
  [LAA] Also reset CanUseDiffCheck in RTPointerChecking::reset().

RuntimePointerChecking::reset() is used to reset its state between
subsequent analysis invocations. Also reset CanUseDiffCheck to its
default (true). Otherwise it might have been set to false during a
previous analysis invocation, which unnecessarily pessimizes the
subsequent analysis invocations with a pruned set of dependences.

This is in line with the other fields being reset.
