Function _mm_mask_shrdv_epi16

#[target_feature(enable = "avx512vbmi2", enable = "avx512vl")]
pub const fn _mm_mask_shrdv_epi16(a: __m128i, k: __mmask8, b: __m128i, c: __m128i) -> __m128i

Concatenate packed 16-bit integers in b and a producing an intermediate 32-bit result. Shift the result right by the amount specified in the corresponding element of c, and store the lower 16-bits in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
