Turns out we can just throw an exception from the signal handler
...
without any fancy tricks.
This has been tested on macos, hopefully it works on linux too.

Try to return an error from call_protected when an exception occurs.
...
Something breaks pretty drastically sometimes, not sure why.

Add a signal handler for macos and linux.
...
Implementation Notes:
- To avoid setjmp, longjmp, and the mess that those create, we instead set the interrupting
context of the signal handler to return into the `throw_trap` routine. To my surprise,
this actually works. The stack ends up getting unwound normally and the memory-oob error
is caught by the trampoline.

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

- 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.

...
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).

* revert to only reserving and not committing memory due to issues
