Presumably, ternaries are good candidates for this. 

boolean isOdd(int i){
    boolean odd=((i%2)!=0)?0:1;
    return odd;

The ConditionalNode is most of the time not created by the GraphBuilder directly, but it will appear later when a simple if/then/else is canonicalized.
So a simple snippet that boils down to a conditional move could look like this:

public static int testSnippet(int i) {
  if (i == 0) {
    return 1;
  } else {
    return 2;
