Add support for computing the exception specification for an inheriting

constructor. This isn't quite perfect (as usual, we don't handle default
arguments correctly yet, and we don't deal with copy/move constructors for
arguments correctly either, but this will be fixed when we implement core issue
1351.

This completes our support for inheriting constructors.
