    MIPS: soft-fp NaN representation corrections

    [BZ #15442] This adds support for the inverse interpretation of the
    quiet bit of IEEE 754 floating-point NaN data that some processors
    use.  This includes in particular MIPS architecture processors; the
    payload used for the canonical qNaN encoding is updated accordingly
    so as not to interfere with the quiet bit.
