Description
The VK_KHR_vulkan_memory_model extension allows use of the features
guarded by the VulkanMemoryModel, VulkanMemoryModelDeviceScope,
and VulkanMemoryModelAvailabilityVisibilityChains capabilities in
shader modules.
The Vulkan Memory Model formally defines how to synchronize
memory accesses to the same memory locations performed by multiple shader
invocations.

Promotion to Vulkan 1.2
All functionality in this extension is included in core Vulkan 1.2, with the
KHR suffix omitted.
However, if Vulkan 1.2 is supported and this extension is not, the
vulkanMemoryModel capability is optional.
The original type, enum and command names are still available as aliases of
the core functionality.
