Make StmtPrinter use DeclPrinter to print all declarations. Merge
declarations in the limited case of an unnamed TagDecl followed by one
or more declarations using that TagDecl directly. Change

OwnedTag with SuppressTag, since it's more convenient to print
declarations from DeclPrinter at the moment.
improvements to declaration printing. Fix pretty-printing for K&R

walks through DeclContexts properly, and prints more of the

via -ast-print, -ast-dump, etc., and also via the new member functions
Decl::dump() and Decl::print().
