    Template Haskell support for unboxed sums
    
    This adds new constructors `UnboxedSumE`, `UnboxedSumT`, and
    `UnboxedSumP` to represent unboxed sums in Template Haskell.
    
    One thing you can't currently do is, e.g., `reify ''(#||#)`, since I
    don't believe unboxed sum type/data constructors can be written in
    prefix form.  I will look at fixing that as part of #12514.
    
    Fixes #12478.
    
    Test Plan: make test TEST=T12478_{1,2,3}
