  - Support initialization of reference members; complain if any
  reference members are left uninitialized.
  - Use C++ copy-initialization for initializing each element (falls
  back to constraint checking in C)
  - Make sure we diagnose when one tries to provide an initializer
  list for a non-aggregate.
  - Don't complain about empty initializers in C++ (they are permitted)
  - Unrelated but necessary: don't bother trying to convert the
  decl-specifier-seq to a type when we're dealing with a C++
  constructor, destructor, or conversion operator; it results in
  spurious warnings.

Fix a stupid mistake in UnwrapSimilarPointers that made any two member pointers compatible as long as the pointee was the same.
Make a few style corrections as suggested by Chris.

dialects properly.

Small cleanup in the handling of user-defined conversions. 

Also, implement an optimization when constructing a call. We avoid
recomputing implicit conversion sequences and instead use those
conversion sequences that we computed as part of overload resolution.

Duplicate-member checking within classes is still a little messy, and
anonymous unions are still completely broken in C. We'll need to unify
the handling of fields in C and C++ to make this code applicable in
both languages.

arguments needs to be deferred until the class definition is complete
(see FIXME in the test).

being called to be converted to a reference-to-function,
pointer-to-function, or reference-to-pointer-to-function. This is done
through "surrogate" candidate functions that model the conversions
from the object to the function (reference/pointer) and the
conversions in the arguments.
