SERVER-13732 rewrite contained $or queries to rooted $or in the SubplanStage
This allows queries with an $or contained within an explicit or implicit $and to be answered with
more efficient plans. It also expands the use of the SubplanStage to include contained $or queries
and therefore may reduce the number of plans considered for these queries.
