Brendon Cahoon 6912fe6f35 [Hexagon] Remove dead constant assignment in hardware loop pass ...

After converting a loop to a hardware loop, the pass should remove
any unnecessary instructions from the old compare-and-branch
code. This patch removes a dead constant assignment that was
used in the compare instruction.
