[code-reflection] Integrated: Hat lanewise binary op extraction experiment

[Gary Frost]

Demonstrate that we can leverage the codemodels of lanewise vector style operations to determine the core binary op used in each lane.

So given

@Reflect
 static XY whoKnows(XY lhs, XY rhs) { #1
     return new XY(lhs.x * rhs.x, lhs.y * rhs.y);
  }
  @Reflect
   public XY whoKnows(XY xy) { // #2
     return whoKnows(this, xy);
   }
``` 
If we find a fluent method which takes a type and returns the type (whoKnows(XY xy)) we can determine the binary op it represents by  'recursivley' traversing the code models from an entrypoint
