----------------
Compositions of MemberExprs/CXXMemberCallExprs have an issue:
```
template <class A1> struct A {
struct Inner {
A1 m;
A1 f();
} inner;
Inner g();
};
Z x1 = A<Int>().inner.m; //No resugar
Z x2 = A<Int>().inner.f(); //No resugar
Z x3 = A<Int>().g().m; //No resugar
Z x4 = A<Int>().g().f(); //No resugar
Z x5 = A<Int>::Inner().m; //ok
```
Composed `CallExprs` seem to work but probably warrant a test, e.g.
```
template <class B1> B1 h(B1);
Z x6 = h(Int());
Z x7 = h(h(Int()));
```
