C++: fix code completion for decltyped type

example:
struct Foo { int bar; };
Foo foo() { return Foo; }
typedef decltype(foo()) TypedefedFooWithDecltype;
void fun()
{
  decltype(foo()) decltypeFoo;
  decltypeFoo.;// code completion should work here

  TypedefedFooWithDecltype typedefedFooWithDecltype;
  typedefedFooWithDecltype.;// code completion should work here
}
