* reflect: implement method-set based AssignableTo and Implements Based on the design from #4376 by aykevl. Fixes #4277, fixes #3580. Co-authored-by: Ayke van Laethem <aykevanlaethem@gmail.com> * builder: update expected binary sizes for reflect changes * Make interface checks similar to invoke, allowing typeImplementsMethodSet and method info to be dropped when reflect is not present * Add more tests that BigGo reflect tests * Even more pruning * Add go/token and net/url to passing tests * Prune even further, I am less happy with this, though * Update size test now that we are smaller * Skip some tests * elide method lists * format, oops * fix tests * Add a panic, pull out constant to keep in sync * Add debug info * Remove code that was leftover from a previous refactor --------- Co-authored-by: Ayke van Laethem <aykevanlaethem@gmail.com>
