    Add support for all top-level declarations to GHCi
    
      This is work mostly done by Daniel Winograd-Cort during his
      internship at MSR Cambridge, with some further refactoring by me.
    
    This commit adds support to GHCi for most top-level declarations that
    can be used in Haskell source files.  Class, data, newtype, type,
    instance are all supported, as are Type Family-related declarations.
    
    The current set of declarations are shown by :show bindings.  As with
    variable bindings, entities bound by newer declarations shadow earlier
    ones.
    
    Tests are in testsuite/tests/ghci/scripts/ghci039--ghci054.
    Documentation to follow.
