I don't know that I do anything to alter the alignment: I'm just using
the "addClause" function of the landingpad. Platform is x86_64 on Linux.
Note that in the JIT my code does work, so my assumption is that I
haven't done something completely wrong, just partially wrong.

I'm looking at code generated by clang from C++, and I notice a few
differences. Are these relevant?
- the clauses are always cast to i8* (I'm using an i64* as that is my
type information)
- the global variable is marked linkonce_odr unnamed_addr
