[PATCH v3 0/3] MR776: vkd3d-shader: Introduce SPIRV_ENVIRONMENT_VULKAN_1_1.

[Conor McCarthy (＠cmccarthy)]

Shader Model 6 wave ops require instructions not available by extension in SPIR-V 1.0, and device support info is found in VkPhysicalDeviceSubgroupProperties, which also has no equivalent by extension in Vulkan 1.0.
