* include Macros.h much earlier: since it takes care of the alignment platform detection, it is needed before we do the vectorization stuff in Eigen/Core !!
...
* kill EIGEN_DONT_ALIGN_HEAP option (one should use EIGEN_DONT_ALIGN)
* rename EIGEN_DONT_ALIGN_STACK to EIGEN_DONT_ALIGN_STATICALLY. hope it's a better name.

you can still use EIGEN_DONT_ALIGN to do both at once.

Added initial NEON support, most tests pass however we had to use some hackish workarounds
...
as gcc on ARM (both CodeSourcery 4.4.1 used and experimental 4.5) fail to
ensure proper alignment with __attribute__((aligned(16))). This has to be
fixed upstream to remove the workarounds.
