This is the same patch I posted a few days ago, a bit modified according to
Uros' recommendation.
Patch fixes false dependencies for vmovss, vmovsd, vrcpss, vrsqrtss, vsqrtss
and vsqrtsd instructions.
Tested on x86-64/Linux, no new test fails, some SPEC 2006/2017 performance
gains.

Please let me know if something is wrong here and should be changed.
