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}
