[PATCH] D37449: [X86][AVX512] _mm512_stream_load_si512 should take a void const* argument (PR33977)

[Simon Pilgrim via Phabricator via cfe-commits]

RKSimon created this revision.

Based off the Intel Intrinsics guide, we should expect a void const* argument.

Prevents 'passing 'const void *' to parameter of type 'void *' discards qualifiers' warnings.
