Basically, test sets SZ flags, where cmp sets SZCO. I want to add an optimizaton using C, so "cmp 0,x" should not be silently replaced by "test x,x".
This patch can be dropped entirely.TEST clears C (which cmp vs 0 would also do). I was mis-remembering INC/DEC which leave C unchanged and thus uninitialized wrt the current operation.
