We have detected a build metrics regression from push:

https://hg.mozilla.org/integration/autoland/pushloghtml?changeset=7a65516025af8c61f0629e208fd68240dde8f010

As author of one of the patches included in that push, we need your help to address this regression.

Regressions:

  ~100KBytes  installer size linux32 pgo      64,011,650.88 -> 64,212,787.00
  >150KBytes  installer size linux64 pgo      63,396,980.88 -> 63,564,321.42
  ~150KBytes  installer size osx-cross opt    67,455,025.12 -> 67,604,085.83

I think this is basically https://bugzilla.mozilla.org/show_bug.cgi?id=1485892#c1 coming back, because bug 1485946 initially accidentally disabled building and including libprio and msgpack on *all* platforms+compilers, rather than only disabling on Windows with MSVC specifically, which is tier-2.

The followup changeset in that bug corrects this on all the tier-1 platforms so I'd expect it to increase by the rough estimate in the bug link above.
