## Description

This extension allows the use of the `SPV_KHR_relaxed_extended_instruction` extension in SPIR-V shader modules.

It adds a new SPIR-V instruction, which allows some usage of forward references in non-semantic instruction sets. This extensions interacts with the `SPV_KHR_non_semantic_info` extension, hence with `VK_KHR_shader_non_semantic_info`.

## New Structures

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceShaderRelaxedExtendedInstructionFeaturesKHR

## New Enum Constants

- `VK_KHR_SHADER_RELAXED_EXTENDED_INSTRUCTION_EXTENSION_NAME`

- `VK_KHR_SHADER_RELAXED_EXTENDED_INSTRUCTION_SPEC_VERSION`

- Extending VkStructureType:

  - VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_RELAXED_EXTENDED_INSTRUCTION_FEATURES_KHR
