Adds a variant with context specialization disabled. Without this, the code I'm
adding is never considered by already existing unit tests since context
specialization is enabled by default and reverts most of the changes.

Please advise if this is a good idea. It will not increase the release checks by
much, but possibly the debug checks.

The optimal thing would be to run only tubofan tests with this mode.
