and put the the next ObjcAtCatchStmt* as part of SubExprs. This fixes a bug with
iterating over the children of ObjcAtCatch, where the next @catch was not
properly being iterated over as a child.
Altered serialization of ObjCAtCatchStmt to reflect this new layout of
its subexpressions, and fixed an ownership issue with the next @catch not
being serialized as an owned pointer.

visits its decls, rather than just creating an "end()" iterator.
Fixed child_end() for statements and expressions to use
child_iterator() to create the end() iterator, rather than just
returning NULL.
Fixed bug in StmtIterator where we did not correctly detect if we had
marched off the end of the ScopedDecls.

that will (soon) allow iteration over the initializers in
declarations. This new iterator mechanism is implemented by the
classes StmtIterator and ConstStmtIterator.
Patched a few files to use "operator++" instead of "operator+" on
child_iterators.
Friendship added in VarDecl to StmtIterator to allow returning a
reference to the initializer within the VarDecl. We may not wish this
as a permanent solution.

as a member function. This function is no longer needed within the CFG
class, and logically belongs to the Stmt class as a predicate for a
Stmt instance.

including the expressions in the case statement itself (not the body of
the case).
This required moving SubStmt out of SwitchCase into CaseStmt and DefaultStmt
respectively. getSubStmt() now is a virtual call for SwitchCase, but is
a direct (static) call for CaseStmt and DefaultStmt.

out of the llvm namespace. This makes the clang namespace be a sibling of
llvm instead of being a child.
The good thing about this is that it makes many things unambiguous. The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier. IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.

Added "global" statistics gathering for Decls/Stmts/Exprs.
Very useful for working with a single file. When we start compiling
multiple files, will need to enhance this to collect stats on a per-module
basis.

Incorporate code review feedback from Chris...
- minor restructure of ParseMemberReferenceExpr logic. The last statement
is now the instantiation of the AST node (which I like a lot and will conform
to throughout Sema).
- declare StmtClassNameTable const.
- reword an error diagnostic.
- install the correct type for ParseSizeOfAlignOfTypeExpr. Added hook in
ASTContext. For now, simply return Context.UnsignedLongTy. Added a FIXME
to revisit (i.e. compute using TargetInfo).

Type Checking...round 2. This checkin "breaks" parsing carbon.h. I imagine
that this will be true for the next week or so. Nevertheless, this round of
changes includes the following:
- Hacked various Expr classes to pass the appropriate TypeRef. Still have
a few more classes to touch.
- Implement type checking for ParseArraySubscriptExpr and ParseMemberReferenceExpr.
- Added a debug hook to derive the class name for Stmt/Expr nodes. Currently a
linear search...could easily optimize if important.
- Changed the name of TaggedType->TagType. Now we have TagType and TagDecl (which
are easier to remember).
- Fixed a bug in StringLiteral conversion I did a couple weeks ago. hadError was
not initialized (oops).
- changed Sema::Diag to return true. This streamlines the type checking code
considerably.
- Added many diagnositics.
This should be it!

This set of changes includes:
- convert ExprCXX.h and add to the Xcode project file.
-- required adding CXXBoolLiteralExpr to StmtNodes.def.
-- required adding visitor support (decl/defn).
- make the class codes in StmtNodes.def explicit (to enable range checking).
-- this required changing all clients of the STMT macro.
- declare the instance data const.
