 Description   

This change will allow the optimization in SERVER-53484 to operate on a larger class of $match's – that optimization cannot currently be applied to a $match with a $expr, because the renaming code does not support $match with $expr.

This will involve changes to db/matcher/expression_algo.cpp.
