Very interesting. I will be pleased to compare it (on OS X) with Apple's Accelerate framework and
with Intel's IPP lib <http://adriaan.biz/intel/ipp.pas.zip>.

I wonder if it is possible to align constants used for shuffling

But that is the code alignment, not the data alignment
<http://www.freepascal.org/docs-html/3.0.0/prog/progsu1.html> ?
Also note that it is the OS that specifies the alignment on the stack, so you probably won't get
32-byte alignment for arrays on the stack.
