Reland "Vulkan: Generate xfb support code in SPIR-V for extension path" This reverts commit d090627616641f7524655627bfd415de6f8af942. Reason for revert: Fixed parent CL Original change's description: > Revert "Vulkan: Generate xfb support code in SPIR-V for extension path" > > This reverts commit d06feeac1e79d6102e01c123a360bc9099d5bba3. > > Reason for revert: > Earlier CL breaks pre-rotation: > https://chromium-review.googlesource.com/c/angle/angle/+/2598584 > > Original change's description: > > 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.
