Optimizes pop/shift on packed arrays. A new implementation was added that's used
by both CacheIR and Warp. This version is simpler, also supports pre-barriers,
and doesn't need a VM call as fallback.

This makes it possible for the next patch to check for non-extensible objects
as part of the other ObjectElements flags checks, instead of having to check
the BaseShape flag separately.
