[Clang][AVX512][Intrinsics] Adding two definitions _mm512_setzero and _mm512_setzero_epi32

[delena]

Why do you need them. Is it a part of API?

[RKSimon]

Tests?

[m_zuckerman]

Yes its API

[RKSimon]

Can you add tests for the existing _mm512_setzero_* intrinsics as well please?

[RKSimon]

LGTM - add test_mm512_setzero_pd() as well if you can.
