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.

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.

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).
