* Define SpecConstrAnnotation in GHC.Exts, and import it from there
Reason: avoid having to link the entire ghc package in modules
that use compile-time annotations:
import GHC.Exts( SpecConstrAnnotation )
{-# ANN type T ForceSpecConstr #-}
It's a kind of bug that the package exporting SpecConstrAnnotation
is linked even though it is only needed at compile time, but putting
the data type declaration in GHC.Exts is a simple way to sidestep
the problem
