[Liftoff] Fix f64 operations with c fallback

In https://crrev.com/c/1044187 we messed up the macro definition, so
the four f64 operations with c fallback were actually never emitted (we
bailed out instead). This went unnoticed, as it does not produce an
error.
This CL reenables these four instructions.
