Refactored error reporting in CheckObjCDealloc and CheckObjCInstMethSignature to use this new bug reporting interface (major code simplification).

Simplify the parser by removing Parser::ParseIdentifierStatement.

Casts from pointers remain a problem. :)

diagnosic+loc info for i-c-e evaluation.

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.

Add some accessors to APValue.

Refactored auditor interface within GRExprEngine and GRCoreEngine to use a "batch auditor" to dispatch to specialized auditors instead of having a separate vector for each audited Expr*.  This not only provides a much cleaner implementation, but also allows us to install auditors for any expression.

  "adds support (de)serialization (from)to (in memory) buffer."

llvm-svn: 53425

current store implementation is now encapsulated by BasicStore.

These changes prompted some long due constification of ValueState. Much of the
diffs in this patch include adding "const" qualifiers.

Simplify the parser a bit by looking at the next token without consuming it (by Preprocessor::LookNext):

-Remove ParseExpressionWithLeadingIdentifier and ParseAssignmentExprWithLeadingIdentifier.
-Separate ParseLabeledStatement from ParseIdentifierStatement.

llvm-svn: 53376

Add Preprocessor::LookNext method, which implements an efficient way to 'take a peek' at the next token without consuming it.

Constraints. These concepts are already present in the current ValueState, but
the implementation is monolothic. Making ValueState more modular opens up new
design choices for customizing the analysis engine.

In the context of the analysis engine, the "Environment" is the binding between
Expr* (expressions) and intermediate symbolic values (RValues).
