cachefriendlyproduct, that should be banned as well as depending on the platform they can give a malloc, and they could happen even with (large enough) fixed size matrices. Corresponding fix in Product.h: cachefriendly is now only used for dynamic matrices -- fixedsize, no matter how large, doesn't use the cachefriendly product. We don't need to care (in my opinion) about performance for large fixed size, as large fixed size is a bad idea in the first place and it is more important to be able to guarantee clearly that fixed size never causes a malloc.
