Disable avoid_false_dep_for_bmi for atom and icelake(and later) core processors.

lzcnt/tzcnt has been fixed since skylake, popcnt has been fixed since
icelake. At least for icelake and later intel Core processors, the
errata tune is not needed. And the tune isn't need for ATOM either.

gcc/ChangeLog:

* config/i386/x86-tune.def (X86_TUNE_AVOID_FALSE_DEP_FOR_BMI):
Remove ATOM and ICELAKE(and later) core processors.
