Adopt ExprEngine and checkers to ObjC property refactoring. Everything was working, but now diagnostics are aware of message expressions implied by uses of properties. Fixes <rdar://problem/9241180>.

[analyzer] Make the entries in 'Environment' context-sensitive by making entries map from
(Stmt*,LocationContext*) pairs to SVals instead of Stmt* to SVals.
This is needed to support basic IPA via inlining. Without this, we cannot tell
if a Stmt* binding is part of the current analysis scope (StackFrameContext) or
part of a parent context.
This change introduces an uglification of the use of getSVal(), and thus takes
two steps forward and one step back. There are also potential performance implications
of enlarging the Environment. Both can be addressed going forward by refactoring the
APIs and optimizing the internal representation of Environment. This patch
mainly introduces the functionality upon when we want to build upon (and clean up).

[analyzer] Do not invalidate arguments when the parameter's
type is a pointer to const. (radar://10595327)
The regions corresponding to the pointer and reference arguments to
a function get invalidated by the calls since a function call can
possibly modify the pointed to data. With this change, we are not going
to invalidate the data if the argument is a pointer to const. This
change makes the analyzer more optimistic in reporting errors.

[analyzer] Migrate argument invalidation from CFRefCount to ExprEngine.
This is a common path for function and C++ method calls, Objective-C messages and property accesses, and C++ construct-exprs.
As support, add message receiver accessors to ObjCMessage and CallOrObjCMessage.

[analyzer] Change the check::RegionChanges callback to include the regions explicitly requested for invalidation.
Also, allow CallOrObjCMessage to wrap a CXXConstructExpr as well.
Finally, this allows us to remove the clunky whitelisting system from CFRefCount/RetainReleaseChecker. Slight regression due to CXXNewExprs not yet being handled in post-statement callbacks (PR forthcoming).

Begin reworking static analyzer support for C++ method calls. The current logic was divorced
from how we process ordinary function calls, had a tremendous about of redundancy, and relied
strictly on inlining behavior (which was incomplete) to provide semantics instead of falling
back to the conservative analysis we use for C functions. This is a significant step into
making C++ analyzer support more useful.

Move some of the logic about classifying Objective-C methods into
conventional categories into Basic and AST. Update the self-init checker
to use this logic; CFRefCountChecker is complicated enough that I didn't
want to touch it.

Split 'include/clang/StaticAnalyzer' into 'include/clang/StaticAnalyzer/Core' and 'include/clang/StaticAnalyzer/Checkers'.
This layout matches lib/StaticAnalyzer, which corresponds to two StaticAnalyzer libraries.

[analyzer] Move the files in lib/StaticAnalyzer to lib/StaticAnalyzer/Core.
Eventually there will also be a lib/StaticAnalyzer/Frontend that will handle initialization and checker registration.
Yet another library to avoid cyclic dependencies between Core and Checkers.
