This first step deals with the consequences of such removal.
The removal itself will happen in stage 2. That step will
add "is" to the prolog module in the library.
compiler/add_pred.m:
Prepare for "is" being in the prolog module.
compiler/options.m:
Add a way to test whether the change to add_pred.m is in the
installed compiler.

bring programming style up to date.
