Thank you, Eli.

Let me do this in the following way, as I did not run compile time benchmarking for LLVM before, I'll land this patch and will monitor http://llvm-compile-time-tracker.com/index.php, if there will be some noticeable regression from my patch I will revert the patch and will think about what to do later.

I've added @nikic to reviewers as he monitored compile time as I know.
