Terminate all dead defs at the dead slot instead of the 'next' slot.

This makes no difference for normal defs, but early clobber dead defs
now look like:

  [Slot_EarlyClobber; Slot_Dead)

instead of:

  [Slot_EarlyClobber; Slot_Register).

Live ranges for normal dead defs look like:

  [Slot_Register; Slot_Dead)

as before.
