Consider making Position(And possibly Range?) IComparable and adding more operator overloads

[ajaybhargavb]

It is fairly common to want to check whether a position appears before or after another and it would be nice to have them be easily comparable(like this) instead of having to check the line and character separately.

Here is an example of where this might be useful.

I think that makes sense.

Should we apply the same thing to Range as well?

We haven't found the need for it yet. Maybe not given Roslyn doesn't do that either, https://github.com/dotnet/roslyn/blob/master/src/Compilers/Core/Portable/Text/LinePositionSpan.cs.
