Provide an "Analysis Scope" for Analyses so checks can either be run on code declarations (bodies) or Objective-C @implementation blocks.

Break off declaration of Analysis enum into Analyses.def. The driver options in
...
clang.cpp now #include these definitions to create the command line options, and
AnalysisConsumer #includes this file to generate the switch statement to create
actions.
Renamed -check-objc-methodsigs to -warn-objc-methodsigs.
The "missing -dealloc" check is now optional: -warn-objc-missing-dealloc

Add new check: -check-objc-methodsigs. This check scans methods in
...
ObjCImplementationDecls and sees if a ancestor class defines a method with the
same selector but with a different type signature. Right now it just compares
return types, and mainly looks at differences in primitive values. The checking
will be expanded in the future.

Have BugReporter::getCFG and BugReporter::getLiveVariables returns pointers instead of references, because they can both fail

on functions we cannot construct full CFGs for yet.

Refactored some of the BugReporter interface so that data such as the ASTContext&, PathDiagnosticClient*, can be provided by an external source.
...
Split BugReporter into BugReporter and GRBugReporter so checkers not based on GRExprEngine can still use the BugReporter mechanism.

GRExprEngine now expects the LiveVariables information to be provided by its creator.

This allows an optimization in AnalysisConsumer where the same LiveVariables information is used between multiple analyses.

Added version of CheckDeadStores that accepts a client-provided LiveVariables object.

Moved logic for -dump-cfg and -view-cfg into AnalysisConsumer.

Renamed -dump-cfg to -cfg-dump, and -view-cfg to -cfg-view. This naming better matches the same options for asts (e.g. -ast-dump).

Added AnalysisConsumer, a meta-level ASTConsumer class to drive various
...
analyses. This potentially is the primordial origins of a Clang-equivalent
"PassManager".
The new AnalysisConsumer interface allows multiple analyses to be run from a
single invocation of Clang.
Migrated the logic of "-warn-dead-stores" and "-warn-uninit-values" to use the
new AnalysisConsumer interface. The new interface results in a significant code
reduction to incorporate an analysis into the Driver.
Updated a test case to (correctly) acknowledge that it contains a dead store
(this check wasn't being performed because it was previously masked by
-warn-uninit-values).
