Daniel Clifford b51053d89e Reland: [builtins] Implement Array.prototype.slice in Torque ... In the process: - add volatile types for FastJSArray and remove the length_fast accessor from JSArray with the application of more rigorous typing. - add micro benchmarks for testing all the interesting slice cases Also update a few assorted places in .tq code to make them more idiomatic. The original version of this patch had an overly agressive assert that has been loosened.
