[PATCH] D16440: [ThinLTO] Link in only necessary DICompileUnit operands

[Mehdi AMINI via llvm-commits]

joker.eph added a comment.

I just checked on one of our projects and my ThinLTO think time improves from 3m31 (211s) to 3m8 (188s), i.e. 10% improvement with the current version of the patch.
(note this is the full link time, including optimization and codegen!)
