Added HashMap::swap and HashSet::swap. WebCore now uses HashSet::swap.
I figured while I was in the neighborhood I might as well add HashMap::swap,
too.

• wtf/HashMap.h: (WTF::::operator): (WTF::::swap):
• wtf/HashSet.h: (WTF::::operator): (WTF::::swap):

Some improvements on my last patch, suggested by Darin.

• history/PageCache.cpp: (WebCore::PageCache::autoreleaseNow): Swap with an empty set instead of building up an array and then calling clear(). This is slightly more efficient and the code is cleaner.
