51cf9dde05 Move SSA value caches to the entry block.
The supporting framework around LLVM will make sure to only compute values once if they
are known to never change. Previously, these values were attempted to be reused from places where
the users may not dominate the creation of the value. To avoid that, they are always created
in the entry block now.

e362b56b07 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.

9cfda6800f Try to return an error from call_protected when an exception occurs.
Something breaks pretty drastically sometimes, not sure why.

caf2205936 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.

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).

fix appveyor installer and build (#224)
* remove exception handler when function returns or throws

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

* appveyor builds for release, caches more, only publish artifact once

Remove debug option from run command.
I was looking into the code and I noticed that this option is not used.
The `debug!` macro is used across the codebase, which looks more ideal.
