[LTO] Move UpdateCompilerUsed.h from lib/ to include/

[davide]

Summary

I plan to use it in lld. Are you OK with moving this to include/ , or there's a particular reason why it should stay in lib/LTO?

Thanks!

[davide]

In particular, this is how I use it: http://reviews.llvm.org/D21577

[mehdi_amini]

Sure!
(Note: this patch is missing the new header and only shows the removed one)

[davide]

Thanks Mehdi!
I'm not sure why phab ate the new header file, but I made sure it was committed upstream =)

I think there is a component on our bugzilla for phabricator bugs. Not sure whether you should file a bug there or on phab's bug tracker, but it's probably worth reporting somehow.
