In order to add a repl to the cli, trynova#323 moved the `initialize_global_object` and `exit_with_parse_errors` functions into a new `helper` module. However, this still left duplicate code between the `eval` and `repl` commands. This patch moves the isolate and realm initialization, as well as the script execution and microtask checkpoint, to a new `CliRunner` struct that lives in the `helper` module. Aside from just refactoring, this patch makes two visible changes related to promise jobs: - When passing multiple files to `eval`, now promise jobs run after each script execution, rather than at the end. - In `repl` mode it used to be that promise jobs were never run. Now, all promise jobs enqueued when running a line of JS are run before the result is printed.

I'd kind of want to land #268 before this. Making GC work would be kind of nice, even if the API is pretty ugly. |
