Enhance heap sra to be substantially more aggressive w.r.t PHI

Add new GRWorkList class that uses two queues:

ProgramPoint:
...
- Added four new ProgramPoint types that subclass PostStmt for use in
GRExprEngine::EvalLocation:
- PostOutOfBoundsCheckFailed
- PostUndefLocationCheckFailed
- PostNullCheckFailed
- PostLocationChecksSucceed
These were created because of a horribly subtle caching bug in EvalLocation
where a node representing an "bug condition" in EvalLocation (e.g. a null
dereference) could be re-used as the "non-bug condition" because the Store did
not contain any information to differentiate between the two. The extra
program points just disables any accidental caching between EvalLocation and
its callers.
GRExprEngine:
- EvalLocation now returns a NodeTy* instead of GRState*. This should be used as the "vetted" predecessor for EvalLoad/EvalStore.
