#[target_feature(enable = "avx512f")]
pub const fn _mm512_mask_slli_epi32(src: __m512i, k: __mmask16, a: __m512i, IMM8: u32) -> __m512i

Shift packed 32-bit integers in a left by imm8 while shifting in zeros, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
