  -- == Description
  --
  -- This extension advertises the SPIR-V @ShaderClockKHR@ capability for
  -- Vulkan, which allows a shader to query a real-time or monotonically
  -- incrementing counter at the subgroup level or across the device level.
  -- The two valid SPIR-V scopes for @OpReadClockKHR@ are @Subgroup@ and
  -- 'Vulkan.Core10.Handles.Device'.
  --
  -- When using GLSL source-based shading languages, the
  -- @clockRealtime*EXT@() timing functions map to the @OpReadClockKHR@
  -- instruction with a scope of 'Vulkan.Core10.Handles.Device', and the
  -- @clock*ARB@() timing functions map to the @OpReadClockKHR@ instruction
  -- with a scope of @Subgroup@.
