Change log for October 21, 2018 Vulkan 1.1.89 spec update:

* Update release number to 89.

Public Issues:

  * Clarify the reference to <<features-limits-mipmapPrecisionBits, mipmap
    precision bits>> in the <<textures-image-level-selection, Image Level(s)
    Selection>> section (public issue 660).
  * Update <<debugging-object-types,VkObjectType and Vulkan Handle
    Relationship>> table with missing types (public pull request 820).
  * Miscellaneous minor markup cleanup (public pull request 822).
  * Fix copy/paste bugs in the description of how implicit
    availability/visibility operations for atomics/barriers are ordered in
    the <<memory-model-availability-visibility-semantics, Availability and
    Visibility Semantics>> section (public issue 823).
  * Add missing shading_rate_image bit from mesh pipeline list in the
    <<synchronization-pipeline-stages-types>> list (public issue 824).

Internal Issues:

  * Clarify that only statically used members of a push constant block need
    to be in the push constant range, and stop referring to block members as
    "`variables`" in the <<interfaces-resources-pushconst, Push Constant
    Interface>> section. This is related to
    https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/340
    (internal issue 1401).
  * Clarify interaction between flink:vkCmdSetDeviceMask and render pass
    control commands in the slink:VkDeviceGroupRenderPassBeginInfo section
    (internal issue 1416).
  * Miscellaneous minor markup cleanup.
  * Remove types defined by `"disabled"` extensions from
    validextensionstructs in the XML processing scripts, so downstream code
    generators don't emit them.
