It's been reported that certain properties such as nextUp are hundreds of times slower than they need to be. This PR adds some benchmarks in preparation for fixing the issue.

@stephentyrone The generic floating-point conversion initializers use nextUp to decide when rounding is tied. Since we're going to be using them a lot more now and no one's picked up the starter bug, I'm just going to go ahead and speed up the whole lot of them.
