    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.
