7b0c4102fa * add a Make* expression type builder to allow the 
construction of generic expressions working
  for both dense and sparse matrix. A nicer solution
  would be to use CwiseBinaryOp for any kind of matrix.
  To this end we either need to change the overall design
  so that the base class(es) depends on the kind of matrix,
  or we could add a template parameter to each expression
  type (e.g., int Kind = ei_traits<MatrixType>::Kind)
  allowing to specialize each expression for each kind of matrix.
* Extend AutoDiffScalar to work with sparse vector expression
  for the derivatives.

f4661e696e Resize is only defined in Matrix and not in MatrixBase. 
I am not sure whether the better fix is to move the resize functions to MatrixBase.

904f35d194 discard vectorization in matrix-vector product when data is not even 
aligned on the scalar type size (e.g., for double on 32 bits system without -malign-double)

bb1cc0d092 after all we're not aligning to 8byte boundary 
keep most of the changes though as they make the code more extensible

d41577819b we were already aligning to 16 byte boundary fixed-size objects that are multiple of 16 bytes; 
now we also align to 8byte boundary fixed-size objects that are multiple of 8 bytes.
That's only useful for now for double, not e.g. for Vector2f, but that didn't seem to hurt. Am I missing something? Do you prefer that we don't align Vector2f at all?
Also, improvements in test_unalignedassert.

fa65b09661 add outerproduct coeff(int,int) method. 
This is needed to make this expression work:
(vec1*vec2.transpose())*vec3
Gael, no objection? Seems to make sense as that's fast.

eeabd18afc Fix compilation of HouseholderQR and ColPivotingHouseholderQR for non-square fixed-size matrices. 
For Colpiv that was just changing MatrixQType to MatrixType in the instantiation of HouseholderSequence.
For HouseholderQR I also re-ported the solve method from Colpiv as there were multiple issues.

765600458b * bump to 2.90.0 now that it's agreed that we're doing eigen3 
---> question: do we change the prefix eigen2/ to eigen3/ now?
       no, better wait until we've also changed the repository name
* more message improvements: "Install Eigen" was unclear as it left
  out other things like the BLAS library

* kill remnants of old binary library option

924b55e9a9 when copying a ReturnByValue into a MatrixBase, first eval it to a PlainMatrixType. 
This allows to limit the number of instantiations of the big template method evalTo.
Also allows to get rid of the dummy MatrixBase::resize().
See "TODO" comment.

e82ab8a5dd move also inverse() to ReturnByValue, by doing a solve on NestByValue<Identity>. 
also: adding resize() to MatrixBase was really needed ;)

c1c780a94f * ReturnByValue:

828a79ac78 allow to override EIGEN_RESTRICT, to satisfy a smart ass blogger who claims 
that eigen2 owes all its performance to nonstandard restrict keyword.
well, this can also improve portability in case some compiler doesn't have __restrict.
