Failing IR

When compiled with llc and then linked with link.exe, the IR attached will
result in a program that exits with status 1 instead of status 0. It looks like
the i64* in @rust_main being live over an invoke to get used in a cleanuppad
may be causing problems, but I'm not quite sure what may be the problem beyond
that!
