I'm replacing this part with a fix to avoid incrementing bool in the
testsuite, because otherwise generate_unique<bool>::build() only ever
returns true. This way it still doesn't return unique values, but at
least it alternates between true and false, and is valid for C++17.

Tested x86_64-linux, committed to trunk.
