Added InvokeBlockIseqDirect HIR with codegen. This is a fastpath for setting up a frame for a block that has an iseq and making a JIT to JIT call to it. This works for `yield` only and not for `block.call` where `block` is the `blockparamproxy`. ``` Performance summary: ┌────────────────┬────────────────────────────────┬────────────────────────────┐ │ Block invoke │ Before (without these changes) │ After (with these changes) │ ├────────────────┼────────────────────────────────┼────────────────────────────┤ │ yield (0 args) │ ~30M i/s │ 50.4M i/s │ ├────────────────┼────────────────────────────────┼────────────────────────────┤ │ yield(1, 2) │ ~30M i/s │ 52.7M i/s │ └────────────────┴────────────────────────────────┴────────────────────────────┘ ```
It is nice to be able to slice out a location in pattern matching without having to explicitly get the location object and call slice manually. Also, construct the response for deconstruct_keys lazily in order to avoid reifying location objects if we don't have to. ruby/prism@3024cb55f2
