[cfe-dev] Trying out SjLj exception handling on Win32

[Ruben Van Boxem]

I've raised the point before, and I know it's not the "right" way for
exceptions on Windows, but 32-bit Windows really has no alternative
(Win64 is different).

I set (unconditionally, only for testing)
ExceptionsType = ExceptionHandling::SjLj;
in X86MCAsmInfoCOFF. This leads to an error message when compiling with clang++:
fatal error: error in backend: Cannot select: intrinsic %llvm.eh.sjlj.lsda

Which is telling me I missed something. I can't find the origin of the
error, or where I should look to make it go away.

Any help is appreciated.
