Analyzer renaming method name ignores operand of method address expression

Version Used: Visual Studio 16.8.2

Steps to Reproduce:

1. In any C# source file, type:

    class A
    {
        private unsafe static void M1()
        {
            var xx = (delegate*<void>)(&M1);
        }
    }

2. Change the name of M1 to M2 and use the "Rename 'M1' to 'M2'" refactoring action in VS.

Expected Behavior:

The expression in the initializer of xx changed to (delegate*<void>)(&M2).

Actual Behavior:

The expression in the initializer of xx remain unchanged as (delegate*<void>)(&M1).
