Do actual DCE in LoopUnroll (try 2)
Recommitting after addressing a missed review comment, and updating an aarch64 test I'd missed.
LoopUnroll does a limited DCE pass after unrolling, but if you have a chain of dead instructions, it only deletes the last one. Improve the code to recursively delete all trivially dead instructions.
