I can't think of anywhere that we would need an OverloadedFunctionDecl
to be a ValueDecl, except to satisfy DeclRefExpr.

I like the idea of making DeclRefExpr only require a NamedDecl. It
allows OverloadedFunctionDecl to shrink considerably, and shouldn't
affect DeclRefExpr at all. Sema::ActOnIdentifierExpr will need a
slight tweak to fill in the OverloadType for OverloadedFunctionDecls,
but that's trivial. Good idea!
