🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 only.

Multiply packed unsigned 52-bit integers in each 64-bit element of b and c to form a 104-bit intermediate result. Add the high 52-bit unsigned integer from the intermediate result with the corresponding unsigned 64-bit integer in a, and store the results in dst using writemask k (elements are copied from k when the corresponding mask bit is not set).
