  Vulkan: Implement new GLSL translator back-end.
  
  The Vulkan GLSL translator back-end will handle validating and
  translating our WebGL/ESSL shaders into Vulkan-specific GLSL.
  
  glslang (the Vulkan one) accepts both GLSL and GLSL ES shaders
  as inputs, and both the desktop and ESSL back-ends give
  incompleteness warnings when used. For now, use the desktop GL
  450 as a target for Vulkan GLSL.
  
  The Vulkan-specific changes are currently only to add locations
  to every vertex input and fragment output.
