Proposed Merge: Core: js-tests module into Core: JavaScript

[Yulia Startsev]

Hi Everyone,

We'd like to inform you of a proposed change to move Core: js-tests into Core: JavaScript. The js/src/tests/ directory represents our internal implementation tests for JavaScript features. There are two reasons for this move:
- It is closely related to the work on the JS Standard Library, and as ownership of the standard library is in Core: JavaScript, it makes sense for this test suite to live there as well.
- This directory will be upstreamed to test262, making the relationship to the standard library even more explicit.

Let me know if there are any questions,

- Yulia Startsev, JavaScript Peer
