9a90689b93 Add preliminary support for throwing and catching uncatchable exceptions.
Additional info:
- WebAssembly "traps" are uncatchable, but are still caught by the trampoline caller.

a6fc06c908 Fix more compiling issues
Specifically:
- Don't truncate the list of local parameters.
- If the default destination in a br_table instruction is a loop, don't pop any results.

f0ac76517a Start running spectests
Additional info:
- Execution is turned off, this is just to make sure the backend can compile the entire specsuite.
- That being said, trampolines are implemented and protected call works (just doesn't protect).
