83aa9c67c7 Replace throw() with noexcept. Unlike throw(), noexcept indicates that the function does not throw.
Before C++17, throw() was equivalent to wrapping the function in a try {} catch
{ std::unexpected(); }. In C++17 throw() was made equivalent to noexcept and
in C++20 throw() was removed.

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.

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.

5760f6006a Start implementing exception handling by adding frame descriptor entry processing.
- Soon, we should be able basic exceptions.

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).
