I was vaguely under the impression that compiler intrinsics were the way
forward for these kind of things and somewhere have a branch where I
started to play with them for VS.  Presumably we'd hide the compiler
specific implementations behind an abstraction.

However, I don't see much point in attempting to optimise things without
measuring what we're trying to optimise, i.e. we need some form of
benchmark.
