    Refactor floating of bindings (fiBind)
    
    This is just a local refactoring.
    
    I originally planned to try floating top-level bindings inwards,
    but I backed off from that leaving only this (harmless) refactoring,
    which has no behavioural effect.
    
    I also make FloatIn into a ModGuts -> ModGuts function; again not
    necessary now, but no harm either.
    
    My attempt also used the new function CoreFVs.freeVarsBind; but
    that too is a plausible refactorig of freeVars, so I left it in too.
