Refactored code to match current style on master. Also fixed a bug where some sse results were not being shifted for high bitdepth. Also increased internal bitdepth for variance to avoid saturation. Also added rounding for variance when computing shifted results. Change-Id: I322bbc1b9abe82c8ef72ab97991720240ddf755c
