[PATCH] D59123: [analyzer] RetainCount: Fix a crash when a function follows retain/autorelease naming convention but takes no arguments.

[Artem Dergachev via Phabricator via cfe-commits]

NoQ added a comment.

The actual crash happens in `RetainCountChecker::evalCall()`:

  912     const Expr *BindReturnTo =
  913         (BSmr == BehaviorSummary::IdentityThis)
  914             ? cast<CXXMemberCallExpr>(CE)->getImplicitObjectArgument()
  915             : CE->getArg(0); // <== here
