To be honest I still don't understand what is the key difference between
these two approaches. Both assume that compiler mangles something twice:
one for collecting implicit abi_tags without outputting name to real stream
and once more time mangling name for real with implicit tags collected on
previous stage. I tested my patch on Richard's example and explained why it
works as it should be.
