AVX implementation for PQC

In the course of our project for the integration of PQC into libgcrypt 
we also plan to provide an AVX2 implementation. As our implementation is 
generally based on the reference implementation, the AVX2 implementation 
would also closely follow the one provided in the reference 
implementation of the respective scheme, i.e. using immintrin.h. We 
plan, however, to create a more unified implementation in that we will 
keep common higher level functions with compile-time switches and for 
the lower level functions that are completely different for AVX2, we 
would create separate files.

Please let me know if that approach sounds suitable for libcrypt and if 
you have any comments.
