bitreverse is not supported at the moment.

It appears CBMC does not have available the bitreverse builtin according to the irep IDs definitions. I will talk to CBMC folks to see what can be done about this, but another approach here is to implement the logic for bit reversal it in RMC.

I have created diffblue/cbmc#6581, which does require further work until it can be merged, but might already suffice to clarify the interface for RMC to use.
