AliasSetTracker.h

  void removeCallSite(CallSite CS) {
    for (size_t i = 0, e = CallSites.size(); i != e; ++i)
      if (CallSites[i] == CS.getInstruction()) {
        CallSites[i] = CallSites.back();
        CallSites.pop_back();
      }
  }


this code is wrong, it caches the size of the vector but it doesn't update the
size after removing an element from the vector

this piece of code fixes it

 void removeCallSite(CallSite CS) {
    for (size_t i = 0; i != CallSites.size(); ++i)
      if (CallSites[i] == CS.getInstruction()) {
        CallSites[i] = CallSites.back();
        CallSites.pop_back();
      }
  }

Thanks,
Miguel
