	Returns true if the location is 'self'.
static SelfFlagEnum	getSelfFlags (SVal val, ProgramStateRef state)
	A call receiving a reference to 'self' invalidates the object that 'self' contains. This keeps the "self flags" assigned to the 'self' object before the call so we can assign them to the new object that 'self' points to after the call.

static bool	hasSelfFlag (SVal val, SelfFlagEnum flag, CheckerContext &C)
static bool	isInvalidSelf (const Expr *E, CheckerContext &C)
	Returns true of the value of the expression is the object that 'self' points to and is an object that did not come from the result of calling an initializer.

A call receiving a reference to 'self' invalidates the object that 'self' contains. This keeps the "self flags" assigned to the 'self' object before the call so we can assign them to the new object that 'self' points to after the call.
