commit bcd989d13072a189b49d9393b0d4b1bbaede9d36

    Generalise type of recently added System.Exit.die
    
    This is a follow-up to 77ea2eb0ab36d1a (re #9016) which added `die` with a
    return type of `IO ()` even though all other functions in System.Exit have
    the more general return type `IO a`. It is assumed this was an oversight in
    the original proposal.
