These two functions are almost identical. Wouldn't it be better to combine them
into a single encrypt/decrypt function, similar to what you have done for the
assembly macros?

Shouldn't we also include a check for the buffer length being less than
AVX_GEN2_OPTSIZE? AVX will not be used in that case either.
