Implementing this would not be difficult, but it would increase the overhead
of debugging hugely; it could double both the time and the code size overheads.
Given that builtins and unifications cannot have implementation errors inside
them, this is too high a price.

The right way to trace builtins is with a selectively used bytecode
interpreter.
