  -----------
  [WebAssembly] Update InstPrinter support for EH

- Updates InstPrinter to handle `catch_all`.
- Makes `rethrow` condition an early exit from the function to make the
  rest simpler.
- Unify label and catch counters. They don't need to be counted
  separately and this will help `delegate` instruction later.
- Removes `LastSeenEHInst` field. This was first introduced to handle
  when there are more than one `catch` blocks per `try`, but this was
  not implemented correctly and not being used at the moment anyway.
- Reenables all tests in cfg-stackify-eh.ll that don't deal with unwind
  destination mismatches, which will be handled in a later CL.
