Find all instances of referring to other code by line number or other non descriptive descriptor in this repo, and fix it.

YES YES!!

I came across such comments multiple times and the line numbers are no longer correct, and then I have zero understanding what it's referring to.

IIRC, some implementations that have such comments were copied to dotnet/sdk repo as well, so we might need to look there as well and make similar fixes.
