/* VkPhysicalDevice requires special treatment by loader.  Firstly, terminator
 * code must be able to get the struct loader_icd  to call into the proper
 * driver  (multiple ICD/gpu case). This can be accomplished by wrapping the
 * created VkPhysicalDevice in loader terminate_EnumeratePhysicalDevices().
 * Secondly, the loader must be able to handle wrapped by layer VkPhysicalDevice
 * in trampoline code.  This implies, that the loader trampoline code must also
 * wrap the VkPhysicalDevice object in trampoline code.  Thus, loader has to
 * wrap the VkPhysicalDevice created object twice. In trampoline code it can't
 * rely on the terminator object wrapping since a layer may also wrap. Since
 * trampoline code wraps the VkPhysicalDevice this means all loader trampoline
