[Hexagon] Incorrectly removing dead flag and adding kill flag

The HexagonExpandCondsets pass is incorrectly removing the dead
flag on a definition that is really dead, and adding a kill flag
to a use that is tied to a definition. This causes an assert later
during the machine scheduler when querying the live interval
information.

Patch by Brendon Cahoon.
