There is a GC before the actual serialization, but I'm not sure we want to
do
the compaction during GC. Since this does not affect the code serializer,
but
only the start-up snapshot, the creation of which is not
performance-critical,
we could add a heap walk in V8::CreateSnapshotDataBlob to find all prototype
info objects to compact them before we actually serialize.
I'd be fine with landing this first and then prettify this in a follow-up.
