- Added a side-table per each token-cached file with the preprocessor conditional stack.  This tracks what #if's are matched with what #endifs and where their respective tokens are in the PTH file.  This will allow for quick skipping of excluded conditional branches in the Preprocessor.
- Performance testing shows the addition of this information (without actually utilizing it) leads to no performance regressions.

Actually distinguish between RecordDecl::field_iterator and RecordDecl::field_const_iterator, propagating the constness down to the FieldDecls.

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 stuff is not used outside Base.td, and with the conversion of the
