pub unsafe fn _mm256_stream_pd(mem_addr: *mut f64, a: __m256d)

This is supported on x86 and target feature avx only.

Moves double-precision values from a 256-bit vector of [4 x double] to a 32-byte aligned memory location. To minimize caching, the data is flagged as non-temporal (unlikely to be used again soon).
