Masked reduction intrinsics are specical cases which don't need to have policy
operand. The mask only affects which elements are read. It doesn't effect the
destination register.
The reduction intrinsics have a dedicated destination operand. If it
is undef, we use tail agnostic. If it not undef we use tail
undisturbed.
