Yes. It's also used in ThreadSafety.cpp, so maybe at some point we may

Compiler bugs, most likely. The one I am proposing has the benefit of
working everywhere we care about, at least as far as it's been used in
thread safety analysis for a few releases (so it also works with MSVC
2013 as well as MSVC 2015).
