Just doing some clean-up: it appears this PR was superseded by #160493 (thanks!).
Therefore, I think we should close this PR, as its contents are already merged and it is inactive.

I'll take the liberty of doing so, but please feel free to re-open as needed (and my apologies if this was the wrong call). 
I think this is the same Bran from MSVC who I've worked with, in which case I'm fairly certain this should be 'ok'. Thanks!
