Vulkan: Generate xfb support code in SPIR-V for extension path The only piece of code that's needed to be generated for the extension path is the following, at the right spot (right before depth correction and pre-rotation): ANGLEXfbPosition = gl_Position; The SPIR-V transformer already has gl_Position loaded for depth correction and pre-rotation, so this change simply adds an OpStore to ANGLEXfbPosition. As a result of this change, @@ XFB-OUT @@ is no longer emitted if the transform feedback extension is supported. With the above code now placed correctly for geometry shaders, transform feedback tests for geometry shaders are enabled.
