José Julián Espina 4b892a931d Implement optional chains (#2390 ) This Pull Request implements optional chains. Example: ```Javascript const adventurer = { name: 'Alice', cat: { name: 'Dinah' } }; console.log(adventurer.cat?.name); // Dinah console.log(adventurer.dog?.name); // undefined ``` Since I needed to implement `Opcode::RotateLeft`, and #2378 had an implementation for `Opcode::RotateRight`, I took the opportunity to integrate both ops into this PR (big thanks to @HalidOdat for the original implementation!). This PR almost has 100% conformance for the `optional-chaining` test suite. However, there's this one [test](`85373b4ce1/test/language/expressions/optional-chaining/member-expression.js`) that can't be solved until we properly set function names for function expressions in object and class definitions.		2 years ago
