Reland "[turbofan] Optimize TrapIf/Unless in BranchElim. and CommonOp-Reducer" 

This is a reland of a3b1233e

Changes compared to original commit:
- Use a more canonical way to replace TrapIf/Unless nodes that always
  trap. This fixes the issue where their outputs were marked dead even
  if they were Merge/Loop nodes.
- Use Throw() over Return() to connect a dangling trap to End().
- Add regression test.
