Implemented 90% functionality of new child_iterator for Stmt objects
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.
