The whole method is basically a sequence of special case checks on the form of the AST and could be improved in terms of readability and debuggability by redoing it to use the pattern matching from AbstractDependenceAnalysis or from ASTPatternUtil or something. It has no known bugs, but the nature of it being a bunch of nigh-unreadable special cases suggests that there may be unhandled corner cases.
