llvm dev - May 2018 - Nios 2 target code ownership

Dear LLVM community,

Currently nobody is appointed as code owner for Nios 2 target. Since I've
already developed a part of it and I'm planning to do more development in
this area in coming weeks,  I would like to volunteer myself to become code
owner for this target. Please let me know if you have anything against,
otherwise I'll add myself to CODE_OWNERS.TXT (I'll wait till the end of
this week for any comments).

Kind regards,
Mateusz Belicki
