docs: This function is used to fixup variables from QNames to stack frame
  indexes at stylesheet build time.
  @param vars List of QNames that correspond to variables.  This list
  should be searched backwards for the first qualified name that
  corresponds to the variable reference qname.  The position of the
  QName in the vector from the start of the vector will be its position
  in the stack frame (but variables above the globalsTop value will need
  to be offset to the current stack frame).
