Range attribute usage leads to confusing inspection

Hey there!

Example code:

```
using UnityEngine;

namespace CodeStage
{
public class JetBrainsBug : MonoBehaviour
{
[Range(5, 100)]
public int value = 10;

private void Update()
{
if (value < 3) // ReSharper: Expression is always false
{
Debug.Log("I'm lesser than 3!");
}
}
}
}
```

if (value < 3) line produces "Expression is always false" inspection with suggestions to remove if or replace it with `false`.
The problem is "value" field can easily be changed outside the JetBrainsBug class to absolutely any value including those which are less than 3.

Here is a simplest example of changing value to 1 from the same class without any warnings:

```
namespace CodeStage
{
public class JetBrainsBug : MonoBehaviour
{
[Range(5, 100)]
public int value = 10;

public int Value
{
get => value;
set => this.value = value;
}

private void Start()
{
value = 1; // possible violation of ValueRange attribute
Value = 1; // silent!
}

private void Update()
{
if (value < 3) // ReSharper: Expression is always false
{
Debug.Log("I'm lesser than 3!");
}
}
}
}
```

Thus this inspection causes confusion and may lead to potential erroneous actions from the programmer especially when working on libraries \ APIs which will be used by other developers.

Reproduce the inspection in a Unity C# project using the JetBrainsBug examples, including the public field and property assignments. Start by locating the Unity Range attribute handling and inspection tests or entry point; done means valid code that can receive out-of-range values no longer produces a misleading always-false warning.
