Obviously API hasn't settled yet. My suggestion is to add "MCStreamer
*Streamer" as an additional argument to addPassesToEmitFile() and
FileType of CGFT_Custom. The problem of passing MCContext to streamer
after its construction requires some work but I don't think it's a hard one.

Anyway predefined set of streamers whether it includes ELF/COFF/whatever
or not is a bad idea.

Thanks for answers again!
