Changed GRExprEngine to pass down a reference to itself when checkers are doing postanalysis. This allows the checker to gather information about the state of the engine when it has finished.

- Exposed the worklist and BlockAborted flag in GRCoreEngine
- Changed postanalysis checkers to use the new infrastructure
