- Fix summary lookup for class methods to now use the (optional)
ObjCInterfaceDecl associated with a message expression. This removes a
long-standing FIXME.
- Partial fix for <rdar://problem/6062730> by stop tracking objects that
are passed to [NSObject performSelector]. These methods are often used
for delegates, which the analyzer doesn't reason about well yet.

extend the number of objects tracked by the retain/release checker by assuming
that all class and instance methods should follow Cocoa object "getter" and
"alloc/new" conventions.

methods, class methods, and property implementations) and instead
place all of these entities into the DeclContext.
This eliminates more linear walks when looking for class or instance
methods and should make PCH (de-)serialization of ObjCDecls trivial
(and lazy).

- Remove stale assertion that was breaking the test suite.
- When popping location contexts, only add a control-flow piece for fileID
locations.

character instead of the entire range for the IfStmt, ForStmt, etc. We may
gradually refine these ranges later, but basically terminator ranges just refer
to the first keyword.

When the StoreManager doesn't reason well about pointer-arithmetic, propagate
the non-nullness constraint on a pointer value when performing pointer
arithmetic uisng ++/--.

into StoreManager::CastRegion. Both methods were practically identical, and this
is core logic that is common to all StoreManagers since it defines the basic
invariants of the abstract memory model.

lazy PCH deserialization. Propagate that argument wherever it needs to
be. No functionality change, except that I've tightened up a few PCH
tests in preparation.

ProgramPoints all the way through to GRCoreEngine.
NSString.m now fails with RegionStoreManager because of the void** cast.
Disabling use of region store for that test for now.

A CodeTextRegion wraps two kinds of data: FunctionDecl* or SymbolRef.
The latter comes from the symbolic function pointer that are generated from
function calls or input data.

functions from the analyzer's perspective but not the compiler's.

"manager of symbolic values", wrapping BasicValueFactory, SymbolManager, and
MemRegionManager. While these individual managers nicely separate functionality
in the analyzer, constructing symbolic values can sometimes be cumbersome
because it requires using multiple managers at once. The goal of this class is
to create some factory methods to create SVals that require the use of these
different managers, thus (hopefully) simplifying the analyzer API for clients.
