Here's 12th subpatch. It introduces VF_512 and VI_512 iterators.
Is it Ok?
Testing:
1. Bootstrap pass.
2. make check shows no regressions.
3. Spec 2000 & 2006 build show no regressions both with and without -mavx512f
option.
4. Spec 2000 & 2006 run shows no stability regressions without -mavx512f
option.

Thanks, K
PS. If it is Ok - I am going to strip out ChangeLog lines from big patch.
