Review Comment:
I think this is very similar to a previous state of this PR but your version
uses an immutable `AttributeMap[(Literal, BinaryComparison)]` instead of a
mutable `Map[Expression, (Literal, BinaryComparison)]` in my PR. The addition
of maps `val equalityPredicates = equalityPredicatesLeft ++
equalityPredicatesRight` inside `And` is slower when we use immutable maps
that's why I proposed to use a mutable one.
But since that version, I changed my PR to eliminate map addition at all and
I use the mutable map as an accumulator from this commit:
