I think this should be done in this patch, because if you run passes manually like:

  $ llc -run-pass pass1 mir0 -o mir1
  $ llc -run-pass pass1 mir1 -o mir2
  $ llc -run-pass pass1 mir2 -o mir3
  $ llc -run-pass pass1 mir3 -o -

You'll end up with 4 vreg entries when only the last one actually matters.
