Speed up AssignmentPattern parsing

I haven't run the full test suite, this isn't ready yet, but it does produce a significant speedup for loading this page. Most real-world destructuring patterns are probably not that big, so while those would still be slow, they shouldn't be as noticeable.

I'll add further fixes to the test suite as needed.

PS, webkit-patch is failing to upload my patches today (https://gist.github.com/caitp/27af5c48cd1758c65784 for a log), so this is just the output from `git format-patch`, hope that's cool.
