  Vulkan: Set set/binding in SPIR-V
  
  This change introduces a SPIR-V transformer that modifies shader
  interface variable decorations directly in SPIR-V instead of
  manipulating the input GLSL.  Currently, descriptor set and binding
  indices are set by the transformer.
  
  The shader translator outputs arbitrary set and binding indices.  Once
  compiled by glslang, the SPIR-V transformer modifies these decorations.
  The ultimate goal is to be able to modify the SPIR-V again when program
  pipeline objects decide a different set/binding is necessary.
