* Implement send with blocks Not that much extra work compared to `opt_send_without_block`. Moved the stack over flow check because it could've exited after changes are made to cfp. * rename oswb counters * Might as well implement sending block to cfuncs * Disable sending blocks to cfuncs for now * Reconstruct interpreter sp before calling into cfuncs In case the callee cfunc calls a method or delegates to a block. This also has the side benefit of letting call sites that sometimes are iseq calls and sometimes cfunc call share the same successor. * only sync with interpreter sp when passing a block Co-authored-by: Maxime Chevalier-Boisvert <maximechevalierb@gmail.com> Co-authored-by: Aaron Patterson <aaron.patterson@shopify.com>
