- moves compiler implementation to "cli/js/compiler/" directory
- moves more APIs to "cli/js/web":
* "console.ts"
* "console_table.ts"
* "performance.ts"
* "timers.ts"
* "workers.ts"
- removes some dead code from "cli/js/"
Following JS ops were moved to separate files in cli/js/ops directory:
- compiler
- dispatch_json
- dispatch_minimal
- errors
- fetch
- fs_events
- os
- random
- repl
- resources
- runtime_compiler
- runtime
- tty
- Exports diagnostic items from `diagnostics.ts` which are missing at
runtime.
- Returns an array of diagnostics, instead of an object with a property
of `items`. This is because of the way Rust deals with certain
structures, and shouldn't be exposed in the APIs.
