This should only happen if you've deliberately opted into handling
exceptions the Windows way, possibly by copy/pasting an existing
implementation without realizing the implications?
There's not really any reason for anything except Windows to do that,
so look in your MCTargetDesc/XYZMCAsmInfo.cpp for where you set
ExceptionsType and change it to DwarfCFI instead.
