[quandary] summaries are access trees too Summary: Previously, summaries worked by flattening the access tree representing the post of the procedure into (in essence) a list of functions from caller input traces to callee output traces. This is inefficient in many ways, and is also much more complex than just using the original access tree as the summary. One big inefficiency of the old way is this: calling `Trace.append` is slow, and we want to do it as few times as possible. Under the old summary system, we would do it at most once for each "function" in the summary list. Now, we'll do it at most once for each node in the access tree summary. This will be a smaller number of calls, since each node can summarize many input/output relationships.

[quandary] skeleton for ObjC traces Summary: Generalized the CppTrace into a Clang trace because we don't currently have separate checkers for Obj-C and Cpp. Happy to separate them later if there is a good reason Reviewed By: akotulski Differential Revision: D4394952 fbshipit-source-id: e288761 8 years ago			`module Clang : module type of (AccessTree.Make(ClangTrace))`
