There is a bit of a corner case here for secondary buffers that don't inherit framebuffer information, since those won't have access to the number of layers in the framebuffer by the time we get here. Since we only emit this to sanitize the value of gl_Layer produced from geometry shaders, I think it is probably fine to lie about it and just use the maximum number of layers we support. The only issue with that is that broken shaders that emit out of bounds layer indices (which the spect states may lead to unfined shading results) may cause undefined results. In the future we could do better and patch the uniform streams later when the secondary is executed inside a primary, since we will have the required framebuffer information at that point, but for now this seems like a reasonable compromise.
