This revision is now accepted and ready to land.

I can see the bloat as we inline with a ridicolously high threshold before instrumenting without DCE'ing, so the patch seems a decent idea. 
Also, DCE is basically free compile-time wise. If you want to improve I'd do it on the DCE side instead of the instrumentation side, but that needs a larger discussion which definitely doesn't fit in the margin of this page.
