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).

expressions, and value-dependent expressions. This permits us to parse
some template definitions.

This is not a complete solution; we're missing type- and
value-dependent computations for most of the expression types, and
we're missing checks for dependent types and type-dependent
expressions throughout Sema.

parameters, with some semantic analysis:
  - Template parameters are introduced into template parameter scope
  - Complain about template parameter shadowing (except in Microsoft mode)

Note that we leak template parameter declarations like crazy, a
problem we'll remedy once we actually create proper declarations for
templates. 

Next up: dependent types and value-dependent/type-dependent
expressions.

Correct CodeGen assumption that LongTy == Int32Ty in a few places. This makes several CodeGenObjC tests pass on 64-bit by fixing assertions. This doesn't mean that the result is actually what the GNU runtime expects, though.

optimizers will do the appropriate optimizations when safe.

uses of getName() with uses of getDeclName().  This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

assert if the name is not an identifier.  Update callers to do the right
thing and avoid this method in unsafe cases.  This also fixes an objc
warning that was missing a space, and migrates a couple more to taking
IdentifierInfo and QualTypes instead of std::strings.

a new NamedDecl::getAsString() method.

Change uses of Selector::getName() to just pass in a Selector 
where possible (e.g. to diagnostics) instead of going through
an std::string.

This also adds new formatters for objcinstance and objcclass
as described in the dox.
