C++11 inheriting constructors: support for inheriting constructor templates.

Don't crash when mangling types defined in ObjC class extensions.

The original test case here was mangling a type name for TBAA,
but we can provoke this in C++11 easily enough.

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.

Handle "typeof" in Objective-C format string checking.  This previously crashed.

Yes, this came from actual code.
