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.
