Author: Jason Ekstrand <[email protected]> Date: Mon Jun 20 23:41:11 2016 -0700 spirv: Use the system value version of gl_FrontFace SPIR-V treats it as an input but NIR wants the system value. This shouldn't have been too much of a surprise given that we have to do the same conversion in the GLSL IR to NIR pass.
