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.
