This is a reland of e3be96d6

The failure was due to not sign extendint the immediate for 64-bit adds on
32-bit platforms.

Original change's description:
> [liftoff] Introduce emit_{i64,i32}_add with immediate
>
> This allows immediates to be encoded directly into instructions, rather than
> mov-ing constants to registers first.
>
> This patch only changes emit_{i64,i32}_add, other emit_ functions will be changed once
> this approach has been approved.
