Conver the rest of the hash functions to use the array-based load instructions.

I'm not totally happy with this - in particular in all cases the size is a
compile time constant - it would be nice to make use of this via tempalate
metaprogramming. Also for matching endian loads, a straight memcpy would
do the work, which would probably be even faster.
