spread-volatile-semantics pass spreads Volatile semantics for builtin variables used by certain execution models based on VUID-StandaloneSpirv-VulkanMemoryModel-04678 and VUID-StandaloneSpirv-VulkanMemoryModel-04679 (See "Standalone SPIR-V Validation" section of Vulkan spec "Appendix A: Vulkan Environment for SPIR-V"). Therefore, shaders without execution model (e.g., used only for linkage) are not the target of the pass. This commit lets the pass just return SuccessWithoutChange in that case.
