Revert "Revert "ART: Update DCE to work with try/catch""

The previous CL failed because it did not update inputs of catch phis.
Since phi input indices cannot be easily mapped back to throwing
instructions, this new implementation at least removes catch phi uses
of values defined in the removed blocks to preserve graph consistency.

This reverts commit fb552d7061746f7a90fdd5002696e255e2e15c35.
