Fixes dotnet#88547

```csharp
using System.Runtime.CompilerServices;

public class ClassA
{
    public virtual int GetValue() => 42;
}

public class ClassB : ClassA
{
    // we don't even need to override GetValue here
}

class MyClass
{
    static void Main()
    {
        Test(new ClassB());
    }

    [MethodImpl(MethodImplOptions.NoInlining)]
    static int Test(ClassA c) => c.GetValue();
}
```

Old codegen:

```
; Method MyClass:Test(ClassA):int (FullOpts)
       sub      rsp, 40
       mov      rax, qword ptr [rcx]
       call     [rax+30H]ClassA:GetValue():int:this
       nop
       add      rsp, 40
       ret
; Total bytes of code: 16
```

New codegen:

```
00007FF66DD8AFB0  cmp         dword ptr [rcx],ecx
00007FF66DD8AFB2  mov         eax,2Ah
00007FF66DD8AFB7  ret
```
