[PATCH] x86: _mm512_set1_p[sd]

[Ulrich Drepper]

Another set of functions missing are those to set all elements of a
512-bit vector to the same float or double value.  I think the patch
below uses the optimal code sequence for that.  The patch requires the
previous patch introducing _mm*_undefined_*.

        * config/i386/avx512fintrin.h: Define _mm512_set1_ps and
        _mm512_set1_pd.
