  Translator: Ensure structs and blocks are uniquely defined
  
  A new AST validation is added to ensure that the same TStructure or
  TInterfaceBlock is not redundantly defined.  This helps with SPIR-V
  generation by allowing the id to be used as key in a hash map that looks
  up the corresponding SPIR-V type id.
  
  A bug is fixed where the Vulkan driver uniform declaration created two
  identical declarations for ANGLEDepthRangeParams.
  
  A number of other bugs are also fixed in this change, where if a
  variable declaration is eliminated (for example due to constant folding,
  or inactive interface variable removal) and it contained a struct
  specifier, the struct declaration was also removed.  OutputGLSLBase had
  a hack where structs were declared on first encounter, which was
  incorrect as the scope of the declaration could change.  Those bugs are
  fixed and this hack is removed.
