Compact zygote.

We now start out using the bump pointer allocator and switch to
the free list collector (ROSAlloc) after the zygote forks.

Before compaction:
Zygote size: 9060352

After compaction
Zygote size: 8425864

The main reason the size doesn't reduce more is that most of the
zygote space is non-movable objects allocated by
VMRuntime.newNonMovableObject. The objects which are non-movable
but could be movable include around 10000 classes and some number
of fields and methods.
