This restores much of the performance benefit of Euler's method, without compromising accuracy (tested on 1e+7 matrices). Namely, my benchmark now runs in 1.5 s instead of 2.2 s. The same in the default branch runs in 1.08 s instead of 1.9 s, so the default branch benefits even more!

Fix 4x4 matrix inversion. Applying Euler's trick is more tricky than what "high performance matrix inversion" websites would have you believe. Our 4x4 matrix inversion wasn't numerically stable, because in applying the Euler trick we didn't take the 2x2 block of biggest determinant. As a result, with float, we got relative errors above 1% every 1000 random matrices, and we got completely wrong results every 10000 matrices.
...
Note that this decreases the performance, but we're still significantly faster than the brutal cofactors approach.

This is now very harmless to do as the big change (EIGEN_ALIGN preprocessor stuff and the body of ei_aligned_malloc) was already introduced in 2.0.6.
Should address Björn's issue, and also improve FreeBSD platform detection.

backported the following to 2.0:
...
* EIGEN_ALIGN and EIGEN_DONT_ALIGN and the corresponding logic in Macros.h
(instead of using EIGEN_ARCH_WANTS_ALIGNMENT)
* The body of ei_aligned_malloc and ei_aligned_free
The reason for this backporting is that a user complained that with eigen 2.0 he got a warning at Memory.h:81 that the return value of posix_memalign was not used, and that function was declared with an attribute warn_unused_result.
Looking at this, it seemed that the body of this function was already overly complicated, and fixing this warning made it even worse, while the devel branch had a much simpler body and didn't suffer from that problem.
Then it was necessary to update ei_aligned_free too, and to backport EIGEN_ALIGN.
Inch' Allah....
