* Eliminate the LiveVarSet class, making applyTranferFuncForMInst a static

  function in the one .cpp file that uses it.  Use ValueSet's instead.
* Prepare to delete LiveVarSet.h & LiveVarSet.cpp
* Eliminate the ValueSet class, making all old member functions into global
  templates that will eventually be moved to Support.
