Query Optimization
To reduce the overheads of copying BSONObj into MatchExpressions, we aim to remove the _backingBSON from the MatchExpression. The MatchExpression will compare against a reference of an already existing BSONObj which survives the query.
Removing _backingBSON, this generates errors in jstests/aggregation/sources/lookup/lookup_foreign_collation.js
e..g, patch
This ticket shall address those errors.
