__cxa_guard_abort along the exceptional edge into (in effect) a nested "try" that rethrows after aborting. Fixes PR7144 and the remaining Boost.ProgramOptions failures, along with the regressions that r103880 caused. The crucial difference between this and r103880 is that we now follow LLVM's little dance with the llvm.eh.exception and llvm.eh.selector calls, then use _Unwind_Resume_or_Rethrow to rethrow. llvm-svn: 103892
