Recurrence of issue #94: Compiler-generated branch for method group caching is not excluded #188

Previously, I reported issue #94, which prevented compiler-generated branches from being ignored when method groups were cached, leading to the inability to reach 100% code coverage.

In recent months, the issue has returned, both in Debug and Release modes, in what appear to be exactly the same circumstances. While I haven't been able to place exactly when it returned -- it's not clear whether moving to the .NET 9 SDK or a particular version of Visual Studio is the culprit -- I can report that I'm experiencing the problem on Visual Studio 17.14.15, in a project targeting net8.0.

See the previous issue for details; the problem now appear to be the same.

Thanks very much!
