Including registers which are not reset in an asynchronous reset process
causes active-low clock-enable flip-flops to be synthesized. This is an
unusual configuration, incurs overhead, and isn't what we wanted to do
anyway. Use a separate process.
While we're at it, sort the bottom half of the if to match the top.
