Change log for June 10, 2019 Vulkan 1.1.111 spec update: 

* Update release number to 111.

Github Issues:

  * Clean up flink:vkGetPhysicalDeviceSurfaceFormatsKHR and
    flink:vkGetPhysicalDeviceSurfaceFormats2KHR to drop the
    ename:VK_FORMAT_UNDEFINED case, require callers pass a supported
    surface, and rearrange some validation-related language (public issue
    207).
  * Allow dynamic and nonuniform indexing of acceleration structures in the
    <<interfaces-resources-descset, Descriptor Set Interface>> section
    (public KhronosGroup/glslang issue 1766).

Internal Issues:

  * Clarify when images require the use of YCbCr samplers for
    slink:VkWriteDescriptorSet and slink:VkImageViewCreateInfo (internal
    issue 1639).
  * Remove the "`block`" language around <<features-robustBufferAccess,
    vectorizing and robust buffer access>> (internal issue 1642).
  * Allow code:OpTypeImageFormat == code:Unknown for input attachments in
    the <<interfaces-resources-descset, Descriptor Set Interface>> section
    (internal issue 1645).
  * Fix asciidoctor conditionals around
    ename:VK_ERROR_FULL_SCREEN_EXCLUSIVE_MODE_LOST_EXT in the
    <<fundamentals-errorcodes>> section (internal issue 1679).
  * Remove error codes from `vk.xml` for
    flink:vkUninitializePerformanceApiINTEL, which has a `void` return type
    (internal issue 1704).
  * Various subgroup-related fixes in the <<spirvenv-capabilities,
    Capabilities>>, <<shaders-subgroup-arithmetic, Arithmetic Subgroup
    Operations>>, <<shaders-subgroup-clustered, Clustered Subgroup
    Operations>>, and <<shaders-subgroup-partitioned, Partitioned Subgroup
    Operations>> sections (internal merge request 3164).
  * Fix asciidoctor markup affecting math rendering in the <<Precision of
    core SPIR-V Instructions>> table (internal merge request 3166).
  * Fix incorrect reference to flink:vkGetPhysicalDeviceFeatures2KHR in the
    description of slink:VkPhysicalDeviceASTCDecodeFeaturesEXT (internal
    merge request 3169).
  * Fix a non-sentence in the introduction to the <<textures, Image
    Operations Overview>> section (internal merge request 3184).
  * Minor markup, grammar, and typo fixes for the
    `<<NV_shader_sm_builtins>>` extension spec language (internal merge
    request 3189).
  * Clarify that 1D and 1D array format support is optional for cubic
    filters, immediately following the <<formats-mandatory-features-astc,
    Mandatory ASTC LDR format support>> table (internal merge request 3194).
