The recent refactoring of SelectorExpr code to helpers broke the handling of MethodExprs when there is an embedded field involved (e.g. test/method7.go, line 48). If there is an embedded field involved, the node op seen in DotMethod() is an ODOT rather than an OTYPE. Also, the receiver type of the result should be the original type, but the new code was using the last type after following the embedding path.
