Initial implementation of argument dependent lookup (a.k.a. ADL,
a.k.a. Koenig lookup) in C++. Most of the pieces are in place, but for
two:
- In an unqualified call g(x), even if the name does not refer to
anything in the current scope, we can still find functions named
"g" based on ADL. We don't yet have this ability.
- ADL will need updating for friend functions and templates.

Allow taking the address of data members, resulting in a member pointer.
Pointers to functions don't work yet, and pointers to overloaded functions even less. Also, far too much illegal code is accepted.

When looking for a tag name via unqualified name lookup, only look in

Content Cache only needs to be 4-byte aligned. Since it is stored in
an std::set, we can't make a strong guarantee about what its alignment
will be. Since I don't need the 3rd bit anyway yet, just change the
assertion.

Steve set me straight on this one. GCC was right, EDG was wrong: the
direct-initialization following a user-defined conversion can select
any constructor; it just can't employ any user-defined
conversions. So we ban those conversions and classify the constructor
call based on the relationship between the "from" and "to" types in
the conversion.

Split specific_decl_iterator, which had a run-time field for

some space in the iterators.

Improve our handling of the second step in a user-defined conversion
sequence. Previously, we weren't permitting the second step to call
copy constructors, which left user-defined conversion sequences
surprisingly broken.
Now, we perform overload resolution among all of the constructors, but
only accept the result if it makes the conversion a standard
conversion. Note that this behavior is different from both GCC and EDG
(which don't agree with each other, either); I've submitted a core
issue on the matter.

Implement and test aggregate initialization in C++. Major changes:
- 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.
