Implementation is based on the "expected type" as used for
designated-initializers in braced init lists. This means it can deduce the type
in some cases where it's not written:

  void foo(Widget);
  foo({ /*help here*/ });

Only basic constructor calls are in scope of this patch, excluded are:

- aggregate initialization (no help is offered for aggregates)
- initializer_list initialization (no help is offered for these constructors)
