  Log Message:
  -----------
  [WebAssembly] Error out for setjmp within catch clause for Wasm SjLj

Wasm EH, used with either of Emscripten SjLj or Wasm SjLj, does not
allow `setjmp` calls to be placed within a `catch` clause, because we
don't support jumping into a `catch` block. Emscripten EH does not have
this restriction. But I think this restriction wouldn't prevent most of
use cases. This CL errors out with a clear messsage for this case.
