RFR: 8295732: Directly embed TruncatedSeqs in G1Analytics

[Thomas Schatzl]

Hi all,

  can I have reviews for this change that directly embeds `TruncatedSeq` into `G1Analytics`. There is no reason imho to use the additional indirection.

This is based on PR#10793, so please review this if not already done.

Testing: local compilation, gha

Thanks,
  Thomas
