ab2b33e802 Add cast to aliasing check. 
Otherwise, one of the geo tests fails to compile. Now there are some compiler
warnings about aliasing and type-punned pointers that I don't understand.

641d968a9a * Make ReturnByValue have the EvalBeforeAssigningBit and explicitly 
enforce this mechanism (otherwise ReturnByValue bypasses it).
 (use .noalias() to get the old behavior.)
* Remove a hack in Inverse, futile optimization for 2x2 expressions.

609941380a Change skipU argument to computeU - this reverses the meaning.

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?

48b8ace517 Fix SparseMatrix/SparseVector::sum() 
SparseMatrix/SparseVector::sum() uses Map to compute the sum. But Map expects a
pointer.

Also remove a print inserted for debugging in schur_real test.

e7d809d434 Update eigenvalues() and operatorNorm() methods in MatrixBase. 
* use SelfAdjointView instead of Eigen2's SelfAdjoint flag.
* add tests and documentation.
* allow eigenvalues() for non-selfadjoint matrices.
* they no longer depend only on SelfAdjointEigenSolver, so move them to
  a separate file

8a3f552e39 Return matrices by constant reference where possible. 
This changes the return type of:
* eigenvectors() and eigenvalues() in ComplexEigenSolver
* eigenvalues() in EigenSolver
* eigenvectors() and eigenvalues() in SelfAdjointEigenSolver

7a43a4408b Replace local variables by member variables in compute() methods. 
This is to avoid dynamic memory allocations in the compute() methods of
ComplexEigenSolver, EigenSolver, and SelfAdjointEigenSolver where possible.
As a result, Tridiagonalization::decomposeInPlace() is no longer used.
Biggest remaining issue is the allocation in HouseholderSequence::evalTo().

17d080edf2 clang shocks on this. 
According to people on #llvm, this is indeed not allowed by c++ standard:

[01:33] <coppro> what good would mutable do on a reference?
[01:33] <dgregor> orzel: gcc is wrong to allow "mutable" on references
[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."
[01:34] <coppro> constness is not passed from an object to the referents of
its members anyways
