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.

  - 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.

the liveness state of block-level expressions could oscillate because
of two issues:
- The initial value before a merge was not always set to "Top"
- The set of live block-level expressions is a union, not an intersection

the C++ definition includes union types.
