    Fix addDataConStrictness · 9014a7ee

    See Note [Add demands for strict constructors].
    The new bit is the test for isAbsDmd in addDataConStrictness.
    There was a cryptic note that said that this function
    should add a seqDmd even for Absent arguments, but that
    is definitely a bad thing (as the Note now says), causing
    unused arguments to be passed to the worker.
    Easy fix!
