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

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)

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 ?

64fbd93cd9 As values may be used uninitialised, they have now been given
sensible defaults; or, in other words, if worse comes to worst,
we'll get a guaranteed segfault rather than a heisenburg.

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
