  Vulkan: Fix precision transformation for geometry shaders
  
  When a varying precision mismatch is present between two stages, the
  SPIR-V transformer transforms the following:
  
      in precision1 type1 inVar;
      out precision2 type2 outVar;
  
      void main()
      {
          f(inVar);
          outVar = g();
      }
  
  to:
  
      in precision3 type1 inVarModified;
      out precision4 type2 outVarModified;
      precision1 type1 inVarTurnedPrivate;
      precision2 type2 outVarTurnedPrivate;
  
      void main()
      {
          // Input preamble
          inVarTurnedPrivate = inVarModified;
  
          f(inVarTurnedPrivate);
          outVarTurnedPrivate = g();
  
          // Output preamble
          outVarModified = outVarTurnedPrivate;
      }
  
  This doesn't work for geometry shaders as they take the varying outputs
  on EmitVertex() as opposed to return from main.  This change simply
  places the output preamble before every EmitVertex() instead of at the
  end of the shader, if it's a geometry shader.
