b2c4501357 Add support for backend flags. Backend flags are opaque to src/bin/wasmer.rs.
Use them to implement three features in the LLVM backend, getting a valid ELF object file, the post-optimization LLVM IR and the pre-optimization LLVM IR.

Presently they are also global to the backend which is not ideal.

c1619026d5 Swap code lazily when tiering up from singlepass to LLVM.
Does not handle long-running functions, but should work at least.

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).
