It's quite common during the compaction cycle to hold series IDs for
series that aren't in the TSDB head anymore.

We shouldn't fail if that happens, as the caller has no way to figure
out which one of the IDs doesn't exist.

Fixes prometheus/prometheus#14278

Adjust the default GOGC value to 75. This is less of a memory savings,
but has less impact on CPU use.

fix: broken link on github mobile

Tune default GOGC

The only call we have to LabelValuesFor() has an index.Postings, and we
expand it to pass to this method, which will iterate over the values.

That's a waste of resources: we can iterate on the index.Postings
directly.

If there's any downstream implementation that has a slice of series,
they can always do an index.ListPostings from them: doing that is
cheaper than expanding an abstract index.Postings.
