[Mesa-dev] [PATCH] i965/gen8: Emit color calculator state whenever viewport changes

[Topi Pohjolainen]

Fixes es3 cts test framebuffer_blit_functionality_scissor_blit.test
on bdw. Viewport changes are tracked by 'brw_cc_vp' which in turn
signals CACHE_NEW_CC_VP that should be tracked by 'brw_cc_unit'. On
gen4 this is the case but not on any newer.

For some reason gen5-7 don't suffer from the missing signaling.
Perhaps one of the mesa states tracked by 'brw_cc_unit'
(_NEW_STENCIL, _NEW_COLOR, _NEW_DEPTH, _NEW_BUFFERS) is
sufficient. Or we are just lucky.
