Load and store the inferred attributes on the analysis summaries. The next step is to use the call stack from performance critical methods to expensive methods form the summary payload instead of modifying the attributes.

Summary: public This diff changes the way we treat enums in Infer.
1. The semantics of the translation is now correct, it was a bit incorrect before.
2. We don't add the enum types to the tenv anymore, which saves a lot of disk space
and avoids errors in the backend dealing with the enum type.

This is an initial version of the Expensive checker which only report violations on direct calls. The main objective is to setup all the files for this new checker.
The next steps are:
1) run the checker in interprocedural mode
2) Save in the summary of a method foo() the annotation attribute Expensive if a direct callee of foo is annotated with Expensive
3) Check that Expensive is enforced by subtyping, i.e. check that non-expensive method cannot be overwritten by a method annotated with Expensive
