It seems like llvmbot didn't CC anyone to ack to backport this time (or yet), so I'll do it manually: @bogner and @zmodem, what do you think about backporting this to the 19.x release?

Also sorry for filing the backport before sorting out buildbot breakage caused by the patch...

@tru - this isn't a very urgent fix wrt the release (for me, I guess it could be for someone else though?), so if you want to keep 19.1.0 extra safe and minimal, feel free to hold off of it for a while. But it's a fix for a clear regression, so I guess it qualifies for 19.x at some point at least. The main impact that I know of, is that one of LLDB's tests on Windows fails, in MSVC configurations, until this issue is fixed.
