cpu_cc_compute_all() has an argument that is always equal to CC_OP for
historical
reasons (dating back to commit a7812ae4123, "TCG variable type checking.",
2008-11-17,
which added the argument to helper_cc_compute_all). It does not make sense for
the
argument to have any other value, so remove it and clean up some lines that are
not
too long anymore.
