11f55b2979 Optimize storage layout of Cwise* and PlainObjectBase evaluator to remove the functor or outer-stride if they are empty. 
For instance, sizeof("(A-B).cwiseAbs2()") with A,B Vector4f is now 16 bytes, instead of 48 before this optimization.
In theory, evaluators should be completely optimized away by the compiler, but this might help in some cases.

5271474b15 Remove common "noncopyable" base class from evaluator_base to get a chance to get EBO (Empty Base Optimization) 
Note: we should probbaly get rid of this class and define a macro instead.

e3f613cbd4 Improve performance of row-major-dense-matrix * vector products for recent CPUs. 
This revised version does not bother about aligned loads/stores,
and rather processes 8 rows at ones for better instruction pipelining.
