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.

Try to return an error from call_protected when an exception occurs.

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).
