class GpuExpressionStats extends AnyRef

A wrapper in place of using Seq[Expression] to record a group of equivalent expressions.

This saves a lot of memory when there are a lot of expressions in a same equivalence group. Instead of appending to a mutable list/buffer of Expressions, just update the "flattened" useCount in this wrapper in-place.
