Optimize ValueSet::Kill
Skip calling DeleteAllImpureWhich for side effects which
MayDependOn will always return false, which happened 65-75% of
the times. In fact, SideEffects::None() was passed on ~50% of
the calls to Kill.
Based on local compiles, this CL improves GVN runtime by ~15% and
overall dex2oat runtime by ~1%.
