Automatic Query Short-Ciruiting

# What problem are you trying to solve?
Sometimes a query can be guaranteed to always return no results. In situations like that, the query should short-circuit and never get sent to the database server.

For Example:
```csharp

var items = (
from x in DbContext.Records
where IdsToFetch.Contains(x.Id)
select x
).ToList();
```

If ```IdsToFetch``` is empty, the query is guaranteed to return no results so it doesnt need to be sent to SQL.

# Describe the solution you'd like
If, client side, a query can be guaranteed to return no results, it should not be sent to the server.

The current alternative that I'm implementing is to manually decorate my code with ```if```s.
