On Darwin, the linker removes functions in CommentDumper.o (Comment::dump())
despite __attribute__(__used__).  As explained by Argyrios,

The fix is to use these functions from another .o file.

Thanks, Argyrios!

Remove trivial destructor from SVal.

This enables the faster SmallVector in clang and also allows clang's unused
variable warnings to be more effective. Fix the two instances that popped up.

The RetainCountChecker change actually changes functionality, it would be nice
if someone from the StaticAnalyzer folks could look at it.

[analyzer] Remove obsolete ObjCPropRef SVal kind.

ObjC properties are handled through their semantic form of ObjCMessageExprs
and their wrapper PseudoObjectExprs, and have been for quite a while. The
syntactic ObjCPropertyRefExprs do not appear in the CFG and are not visited
by ExprEngine.

No functionality change.

[analyzer] Make CallEvent a value object.

We will need to be able to easily reconstruct a CallEvent from an ExplodedNode
for diagnostic purposes, and that's exactly what factory functions are for.
CallEvent objects are small enough (four pointers and a SourceLocation) that
returning them through the stack is fairly cheap. Clients who just need to use
existing CallEvents can continue to do so using const references.

This uses the same sort of "kind-field-dispatch" as SVal, though most of the
nastiness is contained in the DISPATCH and DISPATCH_ARG macros at the end of
the file. (We can't use a template for this because member-pointers to base
class methods don't call derived-class methods even when casting to the
derived class. We can't use variadic macros because they're a C99 feature.)

[analyzer] Rename addExtraInvalidatedRegions to get...Regions

Per Anna's comment that "add..." sounds like a method that modifies
the receiver, rather than its argument.

No functionality change.

[analyzer] Combine all ObjC message CallEvents into ObjCMethodCall.

As pointed out by Anna, we only differentiate between explicit message sends

This also adds support for ObjCSubscriptExprs, which are basically the same
as properties in many ways. We were already checking these, but not emitting
nice messages for them.

This depends on the llvm::PointerIntPair change in r160456.

Force the OS X version to 10.6 for old-style simulator builds.

The hack of recognizing a -D__IPHONE_OS_VERSION_MIN_REQUIRED option
in place of -mios-simulator-version-min leaves the Darwin version
unspecified.  It can be set separately with -mmacosx-version-min (which
makes no sense) or inferred to match the host version (which is unpredictable
and usually wrong).  This really needs to get cleaned up, but in the
meantime, force the OS X version to 10.6 so that the behavior is sane for
the iOS simulator.  Thanks for Argyrios for the patch.
