  1. Merge build-utils-meson/{diagnostics,threads} into build-utils-meson/… 

    …common

This reduces the amount of boilerplate. More importantly, it provides
a place to add compiler flags (such as -O3) without having to add it
to every subproject (and the risk of forgetting to include it).

  2. Use -O3 again 

    This was lost in the switch to the new build system. -O3 provides
around a 10% performance gain compared to -O2, see
e.g. nix-env.qaAggressive.time in
https://hydra.nixos.org/job/nix/master/metrics.nixpkgs#tabs-charts.
