469382407c * Make HouseholderSequence::evalTo works in place 
* Clean a bit the Triadiagonalization making sure it the inplace
  function really works inplace ;), and that only the lower
   triangular part of the matrix is referenced.
* Remove the Tridiagonalization member object of SelfAdjointEigenSolver
  exploiting the in place capability of HouseholdeSequence.
* Update unit test to check SelfAdjointEigenSolver only consider
  the lower triangular part.

faa3ff3be6 tests: 
* change test_is_equal so it just checks for equality, doesn't try anymore to allow to ignoring the difference between col and row vectors.
   (needed for the upcoming Index types change)
 * in ei_assert, don't report on cerr if we're inside of VERIFY_RAISES_ASSERT

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?
