Doxygen comments for avxintrin.h.
Doxygen comments for avxintrin.h.

Added doxygen comments to avxintrin.h's intrinsics. As of now, all the intrinsics in this file that were documented by Sony's intrinsics guide should have corresponding doxygen comments.

Note: The doxygen comments are automatically generated based on Sony's intrinsic
s document.

I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream.

Reviewed by Wolfgang Pieb.
