1. A tiresome change to HsType, to keep a record of whether or not
   the HsForAll was originally explicitly-quantified.  This is
   solely so that the type checker can print out messages that
   show the source code the programmer wrote.  Tiresome but
   easy.

2. Improve reporting of kind errors.
