BuildChildPhysicalProps returns the set of physical properties required of the nth child, based upon the properties required of the parent.

BuildChildPhysicalPropsScalar is like BuildChildPhysicalProps, but for when the parent is a scalar expression.

CanProvidePhysicalProps returns true if the given expression can provide the required physical properties.

DeriveInterestingOrderings calculates and returns the Relational.Rule.InterestingOrderings property of a relational operator.
