[es6] Self-assignment in a default parameter initializer should throw The first bug was that there are two different "initialization positions" passed into PatternRewriter::DeclareAndInitializeVariables, and we weren't setting them all properly for this case. After further code review, it became clear that we weren't even recording the correct position (the end of the initializer expression). The combination of those two bugs caused the hole check elimination code in full-codegen to skip emitting a hole check. This patch takes care of both of those things. A follow-up will try to reduce the number of "initializer positions" we track in the variable declaration code.

Remove destructuring and default arguments runtime flags These flags have been on by default since version 4.9, which has been in stable Chrome for over a week now, demonstrating that they're here to stay.
