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

e9f6167485 make special ei_p functions static to avoid linking issues (they are too 
complex to be inlined)

1b7b538e05 The ABI break: 
* set AutoAlign=0, DontAlign!=0
* set Dynamic=33331
* add check on fixed sizes
* bump version to 2.0.52

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)

62de40f8bb oops forgot to include a file in previous commit (I had other local 
changes I did not want to commit yet...)

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 ?

70c0174bf9 * allows fixed size matrix with size==0 (via a specialization of 
MatrixStorage returning a null pointer). For instance this is very
  useful to make Tridiagonalization compile for 1x1 matrices
* fix LLT and eigensolver for 1x1 matrix

0be89a4796 big addons: 
* add Homogeneous expression for vector and set of vectors (aka matrix)
  => the next step will be to overload operator*
* add homogeneous normalization (again for vector and set of vectors)
* add a Replicate expression (with uni-directional replication
  facilities)
=> for all of them I'll add examples once we agree on the API
* fix gcc-4.4 warnings
* rename reverse.cpp array_reverse.cpp
