This revision is now accepted and ready to land.

LGTM, assuming all tests pass. 
Watch the bots, there could be some build mode (GO?) that can't use .preinit_array but forgets to define  SANITIZER_CAN_USE_PREINIT_ARRAY

I don't know why we did not do this in the past. 
Dmitry may know, but he is OOO and I don't want this to be blocked.
