6466fa63be Reimplement the selection between rotating and non-rotating kernels 
using templates instead of macros and if()'s.
That was needed to fix the build of unit tests on ARM, which I had
broken. My bad for not testing earlier.

b7fc8746e0 Replace a static assert by a runtime one, fixes the build of unit tests on ARM 
Also safely assert in the non-implemented path that should never be taken in practice,
and would return wrong results.

9bd8a4bab5 bug #955 - Implement a rotating kernel alternative in the 3px4 gebp path 
This is substantially faster on ARM, where it's important to minimize the number of loads.

This is specific to the case where all packet types are of size 4. I made my best attempt to minimize how dirty this is... opinions welcome.

Eventually one could have a generic rotated kernel, but it would take some work to get there. Also, on sandy bridge, in my experience, it's not beneficial (even about 1% slower).

a419cea4a0 Created the ptranspose packet primitive that can transpose an array of N packets, where N is the number of words in each packet. This primitive will be used to complete the vectorization of the gemm_pack_lhs and gemm_pack_rhs functions. 
Implemented the primitive using SSE instructions.

01fd880424 Revert previous change and introduce a new workaround regarding gcc generating a shufps instruction instead of the more efficient pshufd instruction. 
The trick consists in introducing a new pload1 function to be used in low level product kernels for which bug #203 does not apply.
Indeed, it turned out that using inline assembly prevents gcc of doing a good job at instructtion reordering.

a96c849c20 Document enums in Constants.h (bug #248). 
To get the links to work, I also had to document the Eigen namespace.
Unfortunately, this means that the word Eigen is linked whenever it appears
in the docs.

9337f371d2 (proper commit this time) 
replaced _mm_prefetch in GeneralBlockPanelKernel.h, with ei_prefetch() inline function.
Implemented NEON and AltiVec versions, copied SSE version over from GeneralBlockPanelKernel.h.
Also in GCC case (or rather !_MSC_VER) it's implemented using __builtin_prefetch().
NEON managed to give a small but welcome boost, 0.88GFLOPS -> 0.91GFLOPS.
