Unifies the name-lookup mechanisms used in various parts of the AST
and separates lexical name lookup from qualified name lookup. In
particular:
* Make DeclContext the central data structure for storing and
looking up declarations within existing declarations, e.g., members
of structs/unions/classes, enumerators in C++0x enums, members of
C++ namespaces, and (later) members of Objective-C
interfaces/implementations. DeclContext uses a lazily-constructed
data structure optimized for fast lookup (array for small contexts,
hash table for larger contexts).

* Implement C++ qualified name lookup in terms of lookup into
DeclContext.

* Implement C++ unqualified name lookup in terms of
qualified+unqualified name lookup (since unqualified lookup is not
purely lexical in C++!)

* Limit the use of the chains of declarations stored in
IdentifierInfo to those names declared lexically.

* Eliminate CXXFieldDecl, collapsing its behavior into
FieldDecl. (FieldDecl is now a ScopedDecl).

* Make RecordDecl into a DeclContext and eliminates its
Members/NumMembers fields (since one can just iterate through the
DeclContext to get the fields).

This reworks some of the Diagnostic interfaces a bit to change how diagnostics
are formed. In particular, a diagnostic with all its strings and ranges is now
packaged up and sent to DiagnosticClients as a DiagnosticInfo instead of as a
ton of random stuff. This has the benefit of simplifying the interface, making
it more extensible, and allowing us to do more checking for things like access
past the end of the various arrays passed in.

In addition to introducing DiagnosticInfo, this also substantially changes how
Diagnostic::Report works. Instead of being passed in all of the info required
to issue a diagnostic, Report now takes only the required info (a location and
ID) and returns a fresh DiagnosticInfo *by value*. The caller is then free to
stuff strings and ranges into the DiagnosticInfo with the << operator. When
the dtor runs on the DiagnosticInfo object (which should happen at the end of
the statement), the diagnostic is actually emitted with all of the accumulated
information. This is a somewhat tricky dance, but it means that the
accumulated DiagnosticInfo is allowed to keep pointers to other expression
temporaries without those pointers getting invalidated.

This is just the minimal change to get this stuff working, but this will allow
us to eliminate the zillions of variant "Diag" methods scattered throughout
(e.g.) sema. For example, instead of calling:

Diag(BuiltinLoc, diag::err_overload_no_match, typeNames,
SourceRange(BuiltinLoc, RParenLoc));

We will soon be able to just do:

Diag(BuiltinLoc, diag::err_overload_no_match)
<< typeNames << SourceRange(BuiltinLoc, RParenLoc));

This scales better to support arbitrary types being passed in (not just
strings) in a type-safe way. Go operator overloading?!
