    StgCmmForeign: Push local register creation into code generation
    
    The interfaces to {save,load}ThreadState were quite messy due to the
    need to pass in local registers (produced with draws from a unique
    supply) since they were used from both FCode and UniqSM.
    
    This, however, is entirely unnecessary as we already have an
    abstraction to capture this effect: MonadUnique. Use it.
