  [RISCV] Update PreprocessISelDAG to use RemoveDeadNodes.

Instead of deleting nodes as we go, delete all dead nodes if a
change is made. This allows adding peepholes that might make
multiple nodes dead.

  Log Message:
  -----------
  [RISCV] Use a switch statement in PreprocessISelDAG. NFC

This should make it easier to add more peepholes in the future.
