8f9d30cb20 * patch from Konstantinos Margaritis: bugfix in Altivec version of ei_pdiv
and various cleaning in Altivec code. Altivec vectorization have been re-enabled
  in CoreDeclaration
* added copy constructors in non empty functors because I observed weird behavior with
  std::complex<>

f0394edfa7 * bugfix in SolveTriangular found by Timothy Hunter (did not compiled for very small fixed size matrices)
* bugfix in Dot unroller
* added special random generator for the unit tests and reduced the tolerance threshold by an order of magnitude
  this fixes issues with sum.cpp but other tests still failed sometimes, this have to be carefully checked...

6d11a07e5e Added a ei_palign function align a packet from two others.
This allows much faster code dealing with unligned as
in the updated matrix-vector product functions.

55aeb1f83a Optimizations:
* faster matrix-matrix and matrix-vector products (especially for not aligned cases)
 * faster tridiagonalization (make it using our matrix-vector impl.)
Others:
 * fix Flags of Map
 * split the test_product to two smaller ones

172000aaeb Add .perpendicular() function in Geometry module (adapted from Eigen1)
Documentation:
 * add an overview for each module.
 * add an example for .all() and Cwise::operator<

516db2c3b9 Fix compilation issues with icc and g++ < 4.1. Those include:
- conflicts with operator * overloads
 - discard the use of ei_pdiv for interger
   (g++ handles operators on __m128* types, this is why it worked)
 - weird behavior of icc in fixed size Block() constructor complaining
   the initializer of m_blockRows and m_blockCols were missing while
   we are in fixed size (maybe this hide deeper problem since this is a
   recent one, but icc gives only little feedback)

22a816ade8 * Fix a couple of issues related to the recent cache friendly products
* Improve the efficiency of matrix*vector in unaligned cases
* Trivial fixes in the destructors of MatrixStorage
* Removed the matrixNorm in test/product.cpp (twice faster and
  that assumed the matrix product was ok while checking that !!)

e27b2b95cf * rework Map, allow vectorization
* rework PacketMath and DummyPacketMath, make these actual template
specializations instead of just overriding by non-template inline
functions
* introduce ei_ploadt and ei_pstoret, make use of them in Map and Matrix
* remove Matrix::map() methods, use Map constructors instead.

c9560df4a0 * add ei_pdiv intrinsic, make quotient functor vectorizable
* add vdw benchmark from Tim's real-world use case

8a967fb17c * implement slice vectorization. Because it uses unaligned
packet access, it is not certain that it will bring a performance
  improvement: benchmarking needed.
* improve logic choosing slice vectorization.
* fix typo in SSE packet math, causing crash in unaligned case.
* fix bug in Product, causing crash in unaligned case.
* add TEST_SSE3 CMake option.

678f18fce4 put inline keywords everywhere appropriate. So we don't need anymore to pass
-finline-limit=1000 to gcc to get good performance. By the way some cleanup.

dca416cace move arch-specific code to arch/SSE and arch/AltiVec subdirs.
rename the noarch PacketMath.h to DummyPacketMath.h
