* Added ReferencableBit flag to known if coeffRef is available.

(needed by the new product implementation)
* Make the packet* members template to support aligned and unaligned
  access. This makes Block vectorizable. Combined with ReferencableBit,
  we should be able to determine at runtime (in some specific cases) if
  an aligned vectorization is possible or not.
* Improved the new product implementation to robustly handle all cases,
  it now passes all the tests.
* Renamed the packet version ei_predux to ei_preduxp to avoid name collision.
