Disable prefetch in AES for now. Problem: with iterative modes like CBC,
the prefetch is called for each block of input, and so a total of
(4096+256)/64 = 68 prefetches are executed for each block. This reduces
performance of iterative modes dramatically.
I'm not sure what the right approach for dealing with this is.
