Operators starting with '>' don't get IDE features

## Current status

It seems that symbols for operators are sometimes picked up for document highlight and inline rename, but it's inconsistent. Given the following code in a .NET Core project:

```fsharp
module Operators =
let (>>=) a f = Result.bind f a
let (<*>) x f = f x
let () = Result.map
let (<+>) x f = f x
let () x f = f x

open Operators

[]
let main argv =
(float (Ok 12)) |> ignore

printfn "Hello World from F#!"
0 // return an integer exit code
```

There three notable issues. Some of these are driven by the same root cause as #3873.

1. Symbols for operators _except_ for `>>=` are picked up. For `>>=`, there is nothing - no QuickInfo, no document highlight, etc.
1. When you try to rename `` at the call site, it will escape the symbol with double backticks.

Note that colorization of `>>=` and any operator that starts with `>` is similarly affected, as per https://github.com/dotnet/fsharp/issues/10272

## Update 2

Modules are now found at the open site by Inline Rename and Find all References due to #3803, thanks @vasily-kirichenko

## Update 1

Using 15.4.1, and given the following code:

```fsharp
module Foo =
let (>.>) x f = f x

open Foo

[]
let main argv =
12. >.> sqrt |> ignore
0 // return an integer exit code
```

Click on `Foo` at the declaration site:

**Epected** --> The `Foo` at `open Foo` is highlighted
**Actual** --> It's not.

Notice that Find Refs and Inline Rename also fail to pick up the symbol.

Click on `>.>` anywhere it's used.

**Expected** --> Highlights the operator everywhere it exists
**Actual** --> No highlight

Find Refs and Inline Rename also do not pick up this symbol.

## Old Issue

VS 2017 15.3 + 8/16/2017 nightly build.

Run Find all References or Rename on `ThisIsAProperty`.

```fsharp
// Learn more about F# at http://fsharp.org
// See the 'F# Tutorial' project for more help.

open TestCS

type C() =
member val ThisIsAProperty = 12 with get, set

[]
let main argv =
let c = C()
c.ThisIsAProperty <- 0
0 // return an integer exit code
```



I don't think that this the same as #3033, because rename and FAR work for the class definition itself.

The above also fails on modules and customer operators.
