This change is a fix / extension of the newbestrefmv experiment. As such it is presented without IFDEF. The change creates a new context for coding inter modes in vp9_find_mv_refs(). This replaces the context that was previously calculated in vp9_find_near_mvs(). The new context is unoptimized and not necessarily any better at this stage (results pending), but eliminates the need for a legacy call to vp9_find_near_mvs(). Based on numbers from Scott, this could help decode speed by several %. In a later patch I will add support for forward update of context (assuming this helps) and refine the context as necessary.
