It's new processor architecture. It doesn't present in GCC sources.

I've took a look through all targets and figured out that there are no targets
who supports cc0 and conditional execution together. So it looks like never
used/tested field.

Also I've met a problem with conditional move and cc0. I get ICE at reload
pass. I don't know what happens. I'm working on it now.
