Hey guys,

Notice that the llvm_ostream doesn't delete the ostream that you pass
into it. If you want to make sure that it's deleted, I think you'll
want to pass in "true" to the WriteBytecodePass so that it'll delete
the llvm_ostream. This won't affect the AsmOutFile, which gets deleted
at the end of the function...
