Fix additional issues reported by UB sanitizers Most of these involved overrunning the signed 32-bit JLONG type whenever building libjpeg-turbo with a 32-bit compiler. These issues are not believed to represent actual security threats, but eliminating them makes it easier to detect such threats should they arise in the future.
