Michael Starzinger 2e007737ca [wasm] Add support for multiple catch blocks. 
This adds support for multiple catch blocks being attached to a single
try block. The implemented semantics are that type checks are performed
in order from top to bottom.

Note that multiple catch blocks of the same type are not prohibited and
will be accepted, making the second such block essentially unreachable.
The current proposal neither explicitly allows nor prohibits it.
