We accidentally broke the ByteCodeParser's constant folding of loads from constants with DFG-watchable structures in http://trac.webkit.org/changeset/188292. The constant folding would happen later, but there are some constant folding rules that only the ByteCodeParser is capable of, particularly with things like CreateThis.
