LLVM 'Code Owners'

Hi Everyone,

It is getting more and more clear that I can't keep up with everything that is happening in the LLVM community ("Chris doesn't scale"). There is too much great stuff happening and I can't review all the code coming in and still have time to write my own contributions.

After discussion with a few people, I've decided to introduce the new concept of an 'owner' of a piece of the code. For more details, see:
http://llvm.org/docs/DeveloperPolicy.html#owners

At this point, this 'change' is really just making official what has been happening for some time now. The good thing about this is that it gives me a chance to officially recognize the significant amount of code review that Evan, Duncan and Anton have been doing over the last couple of years. Thank you guys!
