From ARB_viewport_array spec:
" * On GL3-capable hardware the VIEWPORT_BOUNDS_RANGE should be at least
[-16384, 16383].
* On GL4-capable hardware the VIEWPORT_BOUNDS_RANGE should be at least
[-32768, 32767]."
This range is set using ctx->Const.MaxViewportWidth value, so just bump
those constants to 32k for gen7+ which can support OpenGL 4.0.
