Can't build project

Hi!
I can't compile project on CentOS release 6.6
g++ version:

g++ -v

I believe you need a newer version of GCC. I had the same issue with Ubuntu 12.04, which has an old GCC version. 4.8 seems to work.

@apangin Can we get rid of the __builtin_ia32_pause intrinsic, which isn't supported on older GCC versions? If that's the only blocker, that is. At the very least, we should probably say in the README which GCC version is required to build.

[apangin]

Sure, I'll replace the intrinsic with inline asm
