* 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.

-// This function applies a machine instr to a live var set (accepts OutSet) and

-// used to first kill all defs and then to add all uses. This is because there
-// can be instructions like Val = Val + 1 since we allow multipe defs to a 
-// machine instruction operand.
