e5de9e5226 Remove \nonstable yet. The stability rules for Eigen3 are much simpler: 
- all what's not in unsupported/ is considered stable API
    (except internal stuff e.g. expression templates).

9962c59b56 * implement the corner() API change: new methods topLeftCorner() etc 
* get rid of BlockReturnType: it was not needed, and code was not always using it consistently anyway
* add topRows(), leftCols(), bottomRows(), rightCols()
* add corners unit-test covering all of that
* adapt docs, expand "porting from eigen 2 to 3"
* adapt Eigen2Support

28dde19e40 - Added problem size constructor to decompositions that did not have one. It preallocates member data structures. 
- Updated unit tests to check above constructor.
- In the compute() method of decompositions: Made temporary matrices/vectors class members to avoid heap allocations during compute() (when dynamic matrices are used, of course).

These  changes can speed up decomposition computation time when a solver instance is used to solve multiple same-sized problems. An added benefit is that the compute() method can now be invoked in contexts were heap allocations are forbidden, such as in real-time control loops.

CAVEAT: Not all of the decompositions in the Eigenvalues module have a heap-allocation-free compute() method. A future patch may address this issue, but some required API changes need to be incorporated first.
