Available on (x86 or x86-64) and target feature avx512f,avx512vl and x86 only.
Expand description

Extract 128 bits (composed of 4 packed 32-bit integers) from a, selected with IMM1, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
