Michael Starzinger d56e29d1c0 [wasm] Initial catch-all control flow wiring. 
This adds support to wire control flow of catch-all expressions into an
existing try-catch cascade. Note that multiple typed catch blocks are
not yet supported, only one typed catch block followed by one catch-all
block is supported.

In case the explicit catch-all block is missing, we emulate the correct
semantics by internally always emitting a catch-all containing a simple
rethrow instruction.
