Make line-starts 32-bits TypedData instead of Array of smis.

Make line-starts 32-bits TypedData instead of Array of smis.

While investigating snapshots in kernel it seemed that we stored ~9 bits
per smi we saved for line-starts.

While that is technically true, there also seems to be deduplication at
play, meaning that we in a hello-world example store ~45,000 smis at
~9 bits each, vs when we store TypedData (without deduplication) we
store ~80,000 ints at ~4 bits per entry.

So while this does save ~92 KB it is not at much as was hoped.

I don't know whether this is worth it, given that we save less that what I had
hoped. What do you think? (a hello-world app-jit snappshot goes from ~3.5 MB to
~3.4 MB).

For the curious: While one might think that we would at least save the storage
that all the smis took, as the array entries must still save all references to
the ~80,000 lines.
That's not the case as the references are saved as individual ints which is
stored in a variable number of bytes whereas the typed data entries are stored
directly as bytes and thus takes up 4 bytes a pop.
