[wasm][coreclr] Avoid using calli thunks for delegates #121222
Description
Try to not use calli thunks for code like this:
class Program { static void Main(string[] args) { CountDelegate countDelegate = new CountDelegate(getCount); Console.WriteLine($"count: {countDelegate()}"); Console.WriteLine($"count: {countDelegate()}"); } static double getCount() { return counter++; } static double counter = 0; delegate double CountDelegate(); }We hit an assert, but then the output follows and is as expected, so I think we don't need to use the thunk here and possibly just try to get it during interpreter compilation?
