--- Comment #1 from Xan Lopez <xan.lopez at gmail.com> ---
B3::Compilation is basically:
- A MacroAssemblerCodeRef.
- A vector of opaque "compilation byproducts". This, incidentally, is never used by WasmLLInt (it's always set to null).

I see a few options:
- We could move this to jit/. This would remove the dependency from B3, but would still be a sort of layering violation, since it would make LLInt code depend on jit/ (which is still the case in other places, for now).
- We could move this even further down the stack?
- We could make WasmLLInt use something else when B3 is disabled, and keep the code as-is when B3 is enabled.

I suppose the cleanest solutions in terms of the end result would be either #2 or #1, but comments are welcome.
