2014-12-23rijndael: use more compact look-up tables and add table prefetchingJussi Kivilinna5-3426/+820
* cipher/rijndael-internal.h (rijndael_prefetchfn_t): New.

(prefetch_table, prefetch_enc, prefetch_dec): New. (do_setkey): Setup context prefetch functions depending on selected rijndael implementation; Use new tables for key setup. (prepare_decryption): Use new tables for decryption key setup. (do_encrypt_aligned): Rename to... (do_encrypt_fn): ... to this, change to use new compact tables, make handle unaligned input and unroll rounds loop by two.

AMD64 assembly is slower than before because of additional rotation instructions. The generic C implementation is now better optimized and actually faster than before.
