[GROOVY-7357] Optimized foreach loops should perform a null check

Description

The following code is a regression, because previously the code used an iterator, which in case of null returned an empty iterator. With the optimized path, the loop will fail.

@CompileStatic
private void foo(String[] arr) {
   for (String s in arr) {
      println(s)
   }
}

foo(null)
