We need to skip the check for private memory, otherwise OpenCL CPU device may generate false positive reports due to stack re-use in different threads. However, SPIR-V builts 'ToPrivate' doesn't work as expected on OpenCL CPU device. So we need to manually cleanup private shadow before each function exit point.
