i965: Resolve color and flush for all active shader images in intel_update_state(). 

Fixes arb_shader_image_load_store/execution/load-from-cleared-image.shader_test.

Couldn't reproduce any significant FPS regression in CPU-bound
benchmarks from the Finnish benchmarking system on neither VLV nor BSW
after 30 runs with 95% confidence level.
