42c62c8876 fix #126, part 2/2: the checkTransposeAliasing() assertion was always compiled, for all expressions, 
even for expressions that are known at compile time to not need it because they don't involve any transposing.
This gave 'controlling condition is constant' warnings on ICC, and potentially worse, this could generate a lot
of useless code per-expression if the compiler failed to realize that the condition was constant.

c21390a611 Define non-const operator() in Reverse; enable test for this. 
Introduction of DenseCoeffBase (revision bfdc1c4973
) meant that non-const
operator() is only defined if DirectAccess is set. This caused the line
"m.reverse()(1,0) = 4;" in MatrixBase_reverse.cpp to fail at compile-time.
Not sure this is correct solution; perhaps we should disallow this? Or make
Reverse DirectAccess with a negative stride - would that break something?

[01:33] <coppro> just remove mutable; it won't damage the code at all
[01:34] <dgregor> "The mutable specifier can be applied only to names of
class data members (9.2) and cannot be applied to
[01:34] <dgregor> names declared const or static, and cannot be applied to
reference members."

bfdc1c4973 introduce DenseCoeffsBase: this is where the coeff / coeffRef / etc... methods go. 
Rationale: coeffRef() methods should only exist when we have DirectAccess. So a natural thing to do would have been to use enable_if, but since there are many methods it made more sense to do the "enable_if" for the whole group by introducing a new class. And that also that the benefit of not changing method prototypes.

Adolfo Rodriguez Tsouroukdissian
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.
