Bugs are now reported using a combination of "BugType" (previously
BugDescription) and Bug "BugReport" objects, which are fed to BugReporter (which
generates PathDiagnostics). This provides a far more modular way of registering
bug types and plugging in diagnostics.

GRExprEngine now owns its copy of GRCoreEngine, and is not owned by the
ExplodedGraph.

ExplodedGraph is no longer templated on the "checker", but instead on the state
contained in the nodes.

"BugReporter" and "BugDescription".  BugDescription is used to describe
a bug and provide pieces of the PathDiagnostic, and BugReporter creates
the actual PathDiagnostic by crawling through the ExplodedGraph.

Migrated checks done by GRSimpleVals to be reported using the new BugReporter
mechanism.

GRSimpleVals.h

Added a PathDiagnosticClient option to the driver functions for the
CFRefCountChecker and the GRSimpleVals analysis. Both analyses now accept a "-o"
argument from the driver that specifies where HTML reports should be dumped.

of a stack variable.  This is the path-sensitive version of a check that
is already done during semantic analysis.

llvm-svn: 48980

Added skeleton checking for NSString's method initWithFormat: (do not pass nil).  This won't be useful in most cases right now
because the analyzer isn't tracking expected types for an object, and [NSString alloc] just runs "id".

Added test case to test warning about passing 'nil' to NSString's compare: method.

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.

llvm-svn: 48867

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.
