During fast-isel calling 'markFunctionEnd' in the base class will call tidyLandingPads. This can cause an issue where we have determined that we need ehinfo and emitted a traceback table with the bits set to indicate that we will be emitting the ehinfo, but the tidying deletes all landing pads. In this case we end up emitting a reference to __ehinfo.N symbol, but not emitting a definition to said symbol and the resulting file fails to assemble.
