The reinterpret_casts used in ptranspose(PacketBlock<Packet8cf,4>&) ptranspose(PacketBlock<Packet8cf,8>&) don't appear to be working correctly. They're used to convert the kernel parameters to PacketBlock<Packet8d,T>& so that the complex number versions of ptranspose can be written using the existing double implementations. Unfortunately, they don't seem to work and are responsible for 9 unit test failures in the AVX512 build of tensorflow master. This commit fixes the issue by manually initialising PacketBlock<Packet8d,T> variables with the contents of the kernel parameter before calling the double version of ptranspose, and then copying the resulting values back into the kernel parameter before returning.
