Linq mutator for query syntax

[richardwerkman]

Is your feature request related to a problem? Please describe.
Linq mutations currently only work for Method Style. But query syntax isn't mutated. Example:

            IEnumerable<int> orderingQuery =
                from num in numbers
                where num < 3 || num > 7
                orderby num ascending
                select num;

Describe the solution you'd like
The linq query syntax is fairly limited so we can't mutate a lot. I think we can only mutate:

Original	Mutated
orderby num ascending	orderby num descending
orderby num descending	orderby num ascending
orderby num	orderby num descending

Additional context
The contents of the where in query syntax are already mutated.
