    Make Semigroup a superclass of Monoid (re #14191) · 8ae263ce
    Herbert Valerio Riedel authored
    Unfortunately, this requires introducing a couple of .hs-boot files to
    break up import cycles (mostly to provide class & typenames in order to
    be able to write type signatures).
    This does not yet re-export `(<>)` from Prelude (while the class-name
    `Semigroup` is reexported); that will happen in a future commit.
    Test Plan: local ./validate passed
