RD needs an inspection for variable reassigned but never re-used

[ThunderFrame]

RD already has an inspection for Variable 'x' is not used, which catches this:

Private Sub Test1()
  Dim status As String
  status = foo
End Sub

But it fails to catch unused re-assignments after usage:

Private Sub Test2()
  Dim status As String
  status = "foo"
  Debug.Print status
  status = "bar"
End Sub

This is related to #882, but instead of being a reassignment before use, this inspection is for unused reassignment after prior use.

#882 Value not used is meant to do exactly that
