Thanks! But please include a `ifdef switch that allows those
instructions to be removed (and go back to the previous code).

It's not so much for the small extra resource usage that they would
cause, but meeting timing is a major headache when synthesizing the
complete Milkymist SoC (I'm talking about days of automated runs of the
tools with various sets of options until one happens to work). So I need
to go after every little detail that might break it (or do some
floorplanning which is potentially the right way to solve this, but
placing the logic from each core in separate square boxes actually makes
the timing worse, at least without a lot of careful hand tuning. Maybe
I'm doing it wrong).
