Default to AES u32 being unsinged int and not long. This improves cache
locality on 64-bit platforms (and fixes IA64 assembler-empowered build:-).
The choice is guarded by newly introduced AES_LONG macro, which needs
to be defined only on 16-bit platforms which we don't support (not that
I know of). Meaning that one could as well skip long option altogether.
