    Make ':info Coercible' display an arbitrary string (fixes #12390)
    
    This change enables the addition of an arbitrary string to the output of
    GHCi's ':info'. It was made for Coercible in particular but could be
    extended if desired.
    
    Updates haddock submodule.
    
    Test Plan: Modified test 'ghci059' to match new output.
