Added "GRAuditor" and "GRSimpleAPICheck" interface to allow simple stateless checkers to be injected into the analyzer.
Added "AnnotatedPath" class to record an annotated path that will be useful for inspecting paths.
Added some boilerplate code for simple checks of Apple's Foundation API.

PathDiagnostic no longer contains a diagnostic ID or diagnostic level.

llvm-svn: 48864

Added classes "PathDiagnosticPiece", "PathDiagnostic", and "PathDiagnosticClient", which encapsulate diagnostic reporting for paths.

Bug fix: use GetRVal instead of GetLVal (were getting the value of a DeclRefExpr, not it's address).

Bug fix in transfer function for ObjCMessageExpr: Visit the receiver expression as an ordinary expression, not using VisitLVal.

The effect is that if a variable is uninitialized along a branch (but initialized along another), at merge points it is considered uninitialized.  Previously we had the opposite behavior.  The new behavior is more conservative, and more in line with gcc's behavior.

LiveVariables analysis now uses intersect for the merge of block-level expression liveness information.
The rationale is that a block-level expression cannot be live in a parent block unless it is live in all of the successor blocks.
