Reviewers: scottb,
Description:
Recompute whether an interface is dual-implemented by JSO and Java types
after each compiler optimization pass. Modify CastNormalizer to use
whether or not something is "effectively" JSO (an interface which is
ONLY implemented by a JSO but has not been type-tightened to JSO) as the
criteria for removing casts. Also change isJavaObject to account for
null JSOs (to handle reinterpret cast of null)
