Ted Kremenek 5e1f78aeb1 Refactor DereferenceChecker to use only the new Checker API instead of 
the old builder API.  This percolated a bunch of changes up to the
Checker class (where CheckLocation has been renamed VisitLocation) and
GRExprEngine.  ProgramPoint now has the notion of a "LocationCheck"
point (with PreLoad and PreStore respectively), and a bunch of the old
ProgramPoints that are no longer used have been removed.

Ted Kremenek 2980b975ee Minor cleanup: use BuiltinBug (which will soon be renamed) for DeferenceChecker and friends so that they always report the same bug type.

Ted Kremenek 8d43a6ac3d Merge NullDerefChecker.[h,cpp] and UndefDerefChecker.[h,cpp]. They are essentially two parts of the same check.
