2829314284 new simplified API to fill sparse matrices (the old functions are 
deprecated). Basically there are now only 2 functions to set a
coefficient:
1) mat.coeffRef(row,col) = value;
2) mat.insert(row,col) = value;
coeffRef has no limitation, insert assumes the coeff has not already
been set, and raises an assert otherwise.
In addition I added a much lower level, but more efficient filling
mechanism for
internal use only.

95bda5e6ab let the user disable alignment altogether by #defining EIGEN_DONT_ALIGN. 
Until now, the user had to edit the source code to do that.
Internally, add EIGEN_ALIGN that takes into account both EIGEN_DONT_ALIGN.and
EIGEN_ARCH_WANTS_ALIGNMENT. From now on, only EIGEN_ALIGN should be used to
test whether we want to align.

113fc3a260 now if Derived has the DirectAccess flag, then MatrixBase<Derived>::coeff() const returns a const Scalar& and not a Scalar as before. 
useful for people doing direct access. + 1 bugfix thanks to Patrick Mihelich, forgot a & in MapBase::coeff(int).

2f45eeb0c6 More Cholesky fixes. 
* Cholesky decs are NOT rank revealing so remove all the rank/isPositiveDefinite etc stuff.
* fix bug in LLT: s/return/continue/
* introduce machine_epsilon constants, they are actually needed for Higman's formula determining
  the cutoff in Cholesky. Btw fix the page reference to his book (chat with Keir).
* solve methods always return true, since this isn't a rank revealing dec. Actually... they already did always return true!! Now it's explicit.
* updated dox and unit-test

a1ba995f05 Many improvements in LLT and LDLT: 
* in LDLT, support the negative semidefinite case
* fix bad floating-point comparisons, improves greatly the accuracy of methods like
  isPositiveDefinite() and rank()
* simplifications
* identify (but not resolve) bug: claim that only triangular part is used, is inaccurate
* expanded unit-tests

ce5669dbf9 * enable vectorization of sin, cos, etc. by default with an option to 
disable them (-DEIGEN_FAST_MATH=0)
* add a specialization of MatrixBase::operator*(RealScalar) for fast
  "matrix of complex" times scalar products (even more useful for
  autodiff scalar types)

a22ef7e1f3 for some reason passing the argument by const reference killed the perf 
(in the packet version of sin, cos, exp, lop), so let's pass them by
value. Also, improve the perf of ei_plog by reducing dependencies.

17860e578c add SSE2 versions of sin, cos, log, exp using code from Julien 
Pommier. They are for float only, and they return exactly the same
result as the standard versions in about 90% of the cases. Otherwise the max error
is below 1e-7. However, for very large values (>1e3) the accuracy of sin and cos
slighlty decrease. They are about 3 or 4 times faster than 4 calls to their respective
standard versions. So, is it ok to enable them by default in their respective functors ?
