Partitioned BugTypeCachedLocation::isCached() into two methods: one that accepts and ExplodedNode, and the other that accepts a ProgramPoint.  The default behavior is to cache bug reports by the
location they occur (the end node).  Subclasses can override this behavior by providing a different ProgramPoint.

Rename IsPointerType to LVal::IsLValType, and update CFRefCount::EvalSummary to use IsLValType when conjuring symbols for return values (this fixes a bug with an assertion firing in the analyzer when two qualified objective-c types were compared).

function that returns a CFxxxRef, not just functions whose name begins with
CF.  This implements <rdar://problem/5917879>.

Added test case for this feature.

Updated calls to CStrInCStrNoCase to swap their arguments, per compatibility
with strcasestr.

Correctly check if the result of CStrInCStrNoCase is NULL to generate summaries; before we were inverting the condition.

logic for function calls and message expressions.

Use the following heuristic to infer "allocating" instance methods:

  [ClassName classWithXXX]  allocates an object
  
Update testcase to reflect this heuristic.

the object was last used.  This can be confusing to users.

For example:

 // 'y' is leaked
x = foo(y);

instead:

x = foo(y);
  // 'y' is leaked

Added test case for NSMakeCollectable.

highlight the most nested subexpression that appears most responsible (giving
the user better diagnostic feedback).

Updated test cases to illustrate this feature.
