Reviewed by Darin Adler, Geoffrey Garen and Chris Dumez.

Add the leak tests based on https://chromium.googlesource.com/chromium/blink/+/65db79784ecd4a7e744d10a26befe5159638a56c
These tests have been modified to account for the fact WebKit / JSC uses a conservative GC as opposed to V8's precise GC.
