Finishing touches on code generation for @try and friends.

- declare functions we use.
- cast arguments to objc_exception_match().
- don't take the & of _stack.buf.

Remove old asserts from ASTContext::isObjcIdType() and isObjcClassType(). Instead, return false if the declarations aren't in scope. This was a hold over from when 'id' and 'Class' were initialized lazily.

Added "FIXME" regarding the lack of source location information for IndirectGotoStmt.

Fixed declarations of several "directEmit" methods of classes that subclass
Stmt that were missing a "virtual" keyword.

Teach ASTContext::tagTypesAreCompatible() about the built-in ObjC types (Class and id), removing a bogus warning.

Rewrite ObjC @try/@catch/@finally. Some minor tweaks to the AST nodes...

Still need to rewrite @throw (and do more testing)...

This is far from complete.

by value.  This version prohibits backpatching of pointers, so it
useful when a pointee is always known to be deserialized beforehand.

Reordered stmt serialization method implementations to be in alphabetical order.

Much improvement in exception handling.

is not yet complete.

deserialization code of objects containing QualTypes.
