Does 7.0-BETA2 still have debug options like 6.0-BETA did?

[Yuri]

When 6.0 was in BETA kernel had many options like WITNESS/INVARIANTS. User-land
also has some special options. Those options made FreeBSD-BETA much slower.

Are any similar options "on" now in 7.0-BETA2? What is the complete list?

I can only find an option "makeoptions DEBUG=-g" in sys/i386/conf/GENERIC.

But it feels slower than 6.3.
