Expand description

Concatenate packed 32-bit integers in a and b producing an intermediate 64-bit result. Shift the result left by the amount specified in the corresponding element of c, and store the upper 32-bits in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
