Comment (by Simon Peyton Jones <simonpj@…>):

 In [changeset:"03d4852658e1b7407abb4da84b1b03bfa6f6db3b/ghc"

 Introduce tcTypeKind, and use it

 In the type checker Constraint and * are distinct; and the function
 that takes the kind of a type should respect that distinction
 (Trac #15971).

 This patch implements the change:

 * Introduce Type.tcTypeKind, and use it throughout the type
   inference engine

 * Add new Note [Kinding rules for types] for the kinding
   rules, especially for foralls.

 * Redefine
     isPredTy ty = tcIsConstraintKind (tcTypeKind ty)
   (it had a much more complicated definition before)

 Some miscellaneous refactoring

 * Get rid of TyCoRep.isTYPE, Kind.isTYPEApp,
   in favour of TyCoRep.kindRep, kindRep_maybe

 * Rename Type.getRuntimeRepFromKind_maybe
   to getRuntimeRep_maybe

 I did some spot-checks on compiler perf, and it really doesn't
 budge (as expected).
