011b0f5c5a Make the parameter count of ObjCMethodDecl unsigned, you 
can't have negative arguments.

5072bae709 Switch over functiondecl. This makes it obvious that the ASTContext 
argument to Create should be first, not last.

a7b3287760 start switching decls over to using an allocator controlled by ASTContext. 
Right now only some ctors are switched over.  I need to switch them all
over so I can change the dtor over.

This lets us experiment with region allocation and other things in the 
future.

7b00d15bc5 Path-sensitive analyses no longer take a FunctionDecl, but any Decl representing 
a block of "code".

Patched various ASTConsumers (such as ASTDumper) to have more support for
processing ObjCMethodDecl. CFGVisitor now builds CFGs for ObjCMethodDecls.

1fdd0a480e The LiveVariables analysis no longer requires a FunctionDecl&; this allows it 
to be run on other declarations of blocks of code (e.g., Objective-C methods.)

b64d183803 Added bandaid support in CFG construction for ObjCForEachStmt and ObjCAtTryStmt: 
we gracefully back out and return NULL for the CFG, allowing clients to skip
analyzing functions with these CFGs. We will add support later.

Modified base ASTConsumer "CFGVisitor" to detect when a CFG is not constructed
and to emit a warning.

35cb7960e3 Two fixes to RewriteTest::RewriteObjCIvarRefExpr(): 
- For explicit ivar refers, make sure the cast is propagated to the AST.
- Don't free the base (since it is still in use).
This fixes the recent regression to test/Rewriter/objc-ivar-receiver-1.m.

9f33bd2c34 Avoid using the "unnamed struct field" extension (enabled with -fms-extensions). This feature/extension silently does the wrong thing in g++. As far as I can tell, g++ simply throws the field away entirely (note that it works fine with gcc). Since I am now always casting the object (for other reasons), accessing protected/public fields simply requires the cast refer to the defining class. This solution is simpler all around (thanks to Chris for suggesting it).

dc5b6b2e5d Make ivar rewrite C++ friendly (since C++ forces a unified namespace for typedefs/structures). The previous version of the rewriter generated both a type def and structure def for each class (which doesn't fly in C++).

2bdd77696e Added --trim-path-graph to the driver to trim paths from the ExplodedGraph 
that are not related to error nodes.

Fixed bug where we did not detect some NULL dereferences.

Added "ExplodedGraph::Trim" to trim all nodes that cannot transitively reach
a set of provided nodes.

Fixed subtle bug in ExplodedNodeImpl where we could create predecessor
iterators that included the mangled "sink" bit.  The better fix is to integrate
this bit into the void* for the wrapped State, not the NodeGroups representing
a node's predecessors and successors.

855d024a83 Remove the first layer of support for "portability" warnings. This is 
theoretically useful, but not useful in practice.  It adds a bunch of 
complexity, and not much value.  It's best to nuke it.  One big advantage
is that it means the target interfaces will soon lose their SLoc arguments
and target queries can never emit diagnostics anymore (yay).  Removing this
also simplifies some of the core preprocessor which should make it slightly
faster.

Ted, I didn't simplify TripleProcessor, which can now have at most one
triple, and can probably just be removed.  Please poke at it when you have
time.

184adbfe5b Find clang headers in the clang headers dir, search it before 
the system headers dir.  This produces an annoying warning:
clang.cpp:883: warning: ISO C++ forbids casting between pointer-to-function and pointer-to-object

I'm not sure how to remove it. :(

86e793937a Running -grsimple now emits diagnostics about the time spent analyzing each function. Will 
probably make this a separate command line option later.

Added "--analyze-function" option to the driver to (gradually) allow different
analyses to only be run on specific functions. Currently only --grsimple uses
this option.
