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
SuppressTypeSpecifiers to the more general SuppressSpecifiers, and 
use it to suppress stuff like "typedef" and "extern".  Replace 
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 
function definitions and __builtin_va_arg.

We're now to the point where the pretty-printing output for non-trivial 
programs can actually be piped back into clang.

Add a member lookup criteria constructor for searching for overridden virtual member functions. Use this instead of regular name lookup when checking for overriding functions so we will see declarations that would otherwise be hidden. Fixes 6902298.

move to DeclPrinter.cpp, but I haven't quite worked out how best to do 
that.

walks through DeclContexts properly, and prints more of the
information available in the AST. The functionality is still available
via -ast-print, -ast-dump, etc., and also via the new member functions
Decl::dump() and Decl::print().

printing logic to help customize the output. For now, we use this
rather than a special flag to suppress the "struct" when printing
"struct X" and to print the Boolean type as "bool" in C++ but "_Bool"
in C.

instantiation of tags local to member functions of class templates
(and, eventually, function templates) works when the tag is defined as
part of the decl-specifier-seq, e.g.,

  struct S { T x, y; } s1;

Also, make sure that we don't try to default-initialize a dependent
type.
