For the below test:

  typedef float __attribute__((__vector_size__(16))) f4;
  f4 get();
  int main() {
     float MyVar = get()[0];
     if (MyVar)
       return 1;
  }

Debug location information for 'MyVar' is missing with -O2.

Check that Machine CSE correctly handles during the transformation, the
debug location information for local variables.
