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

 In [changeset:"08ba691ad55f30e67466628125244392c48ce1ab/ghc" 08ba691/ghc]:

 Take account of kinds in promoteTcType

 One of the ASSERT failures in Trac #12762, namely the one for T4439,
 showed that I had not dealt correctly with promoting the kind of
 a type in promoteTcType.

 Happily I could fix this by simplifying InferRes (eliminating the
 ir_kind field), so things get better. And the ASSERT is fixed.
