Spin-off issue from bug 9159.

Between DeclDefs and function body scopes, semantic analysis works differently
for variable declaration.

----
version = A; // or B

struct P {
    int v;
    this(int i) { v = i; }
}

P p(int i) {
    assert(0);
    return typeof(return)(i);
}

class C {
  version(A)
    P p = p(10);    // Error: struct P does not overload ()
}

void main() {
  version(B)
    P p = p(10);    // asserts in runtime
}
----

In the semantic analysis for the expression p(10),
- `p` matches the declared variable itself in DeclDefs scope (version=A).
- `p` matches the module level function in function scope (version=B).
