sdong ddd41146c4 MergingIterator uses autovector instead of vector 
Summary:
Use autovector in MergingIterator so that if there are 4 or less child iterators in it, iterator wrappers are inline, which is more likely to be cache friendly.

Based on one test run with a shadow traffic of one product, it reduces CPU of MergingIterator::Seek() by half.

Test Plan: make all check
