* gcc.target/i386/avx512dq-pr85918.c: Add -mprefer-vector-width=512
and -fno-vect-cost-model options. Add aligned(64) attribute to the
arrays. Add suffix 1 to all functions and use 4 iterations rather
than N. Add functions with conversions to and from float.
Add new set of functions with 8 iterations and another one
with 16 iterations, expect 24 vectorized loops instead of just 4.
* gcc.target/i386/avx512dq-pr85918-2.c: New test.
