Description

Consider the following:

@groovy.transform.CompileStatic
void test(ref) {
  if (ref === null) {
    //...
  }
}

The null check is written as a call to ScriptBytecodeAdapter#compareIdentical. For "ref == null" direct null-comparison bytecode is generated. There may also be opportunities for constant or reference-to-reference comparisons as well.
