Per https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Library/BaseMemoryLib.h
"(CopyMem) must handle the case where SourceBuffer overlaps DestinationBuffer".

Having the gnu-efi version of CopyMem differ from the EDK2 version can lead to
extremely hard to troubleshoot issues as well as very unexpected results. So
make sure our version follows the same guidelines.
