Removes the stutters comming from the film shader. The number of samples used by the film shader is set throught a specialization constant. Since the number of effective sample can depend on jitter position, this number was fluctuating and trigger compilation on new specialization until all specialization were encountered. Rounding the samples up to the most common sample count fixes the issue. Pull Request: https://projects.blender.org/blender/blender/pulls/139154
