Previously `catch_all` shared an opcode with `else`, but the spec now allocates it the 0x19 opcode.
Previously this had interpreted the rethrow depth argument as counting only catch blocks, but the spec has clarified that it should count all blocks (in a similar fashion as `br` and related instructions).

@takikawa It seems you does have the merge access though? You are shown as a "member". Last time I merged your PR because you were shown as a "contributor". I guess you joined the WebAssembly org in the meantime? |

Thanks for the merge! @aheejin I did indeed join the org as a member, maybe I also need to request to join a team in the org? I didn't see the merge button in my UI as far as I could tell. |

This PR updates exception handling support to match the most recent spec explainer (see WebAssembly/exception-handling#137). In particular, it fixes the handling of
rethrow's depth argument and changes thecatch_allopcode. Tests are also expanded (with test cases taken from spec issue examples).
