Add some opcodes for compound logic operations that were so
far marked as TODO. Implement those for PPC and S390X.
We do not want to implement 512-bit width operations, because
those trigger a cluster clock slowdown on the current set of
Intel cpus. But there are new operations in avx512 that apply
to 128 and 256-bit vectors, which do not trigger the slowdown,
and those are very interesting.
