Summary Investigate reducing initial capacity of Partition::m_sets

Investigate whether Partition::initialize(), <https://trac.webkit.org/browser/trunk/Source/WebCore/contentextensions/DFAMinimizer.cpp?rev=209399#L80>, is reserving too much initial capacity for Partition::m_sets. We should also investigate if Partition::m_sets ever holds more items than its initial capacity. If it never holds more items than its initial capacity then it would be more efficient to implement Partition::addSetUnchecked() in terms of Vector::uncheckedAppend() instead of Vector::append() as the former avoids a bounds check.
