IPP and split complex block layout

Trying out Don's elementwise.cpp tests I now get (expected) errors with
IPP, since its elementwise functions assume interleaved format, i.e.
complex<T> *, instead of std::pair<T*,T*>.
The attached patch adds a ct-check to make the evaluator fail on complex
split blocks.
Regards,
Stefan
