    aix: align double complex

    AIX word-aligns floating point doubles.  This behavior also extends to
    double _Complex, which had been overlooked when compiler support for
    double _Complex was added.

    This patch adds DCmode to the modes whose alignment is adjusted and
    adds a testcase to confirm the correct alignment.
