We don't need that.
Unwinding the stack through C functions and code that isn't exception-safe in
the first place is stupid. The only sane outcome of doing that is a crash.
What's more, all Qt libraries aside from QtCore and QtXmlPatterns are built
with exceptions disabled. That means that if your code leaks an exception
through a GUI event loop or a signal from one of those classes, the
application will crash.
So we don't need SJLJ.
