Avi Kivity 05cec4a265 Merge "Reduce LSA memory reclamation overhead" from Tomasz ...

"
Main optimization is in the patch titled "lsa: Reduce amount of segment compactions".

I measured 50% reduction of cache update run time in a steady state for an
append-only workload with large partition, in perf_row_cache_update version from:

  c3f9e6ce1f/tests/perf_row_cache_update.cc

Other workloads, and other allocation sites probably also could see the
improvement.
