fix(clif-backend) Module::new
does not use its argument.
...
The `Module::new` method requires an argument (`wasm: &[u8]`) that is
never used.
This patch removes the argument, and updates the code accordingly.

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.

without any fancy tricks.
This has been tested on macos, hopefully it works on linux too.

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.
