ac7e4ac9c0 Initial commit to add a generic indexed-based view of matrices. 
This version already works as a read-only expression.

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.

6a5fe86098 Complete rewrite of column-major-matrix * vector product to deliver higher performance of modern CPU. 
The previous code has been optimized for Intel core2 for which unaligned loads/stores were prohibitively expensive.
This new version exhibits much higher instruction independence (better pipelining) and explicitly leverage FMA.
According to my benchmark, on Haswell this new kernel is always faster than the previous one, and sometimes even twice as fast.
Even higher performance could be achieved with a better blocking size heuristic and, perhaps, with explicit prefetching.
We should also check triangular product/solve to optimally exploit this new kernel (working on vertical panel of 4 columns is probably not optimal anymore).

58146be99b bug #1004: one more rewrite of LinSpaced for floating point numbers to guarantee both interpolation and monotonicity. 
This version simply does low+i*step plus a branch to return high if i==size-1.
Vectorization is accomplished with a branch and the help of pinsertlast.
Some quick benchmark revealed that the overhead is really marginal, even when filling small vectors.
