DenseSet used to be implemented as DenseMap<Key, char>, which usually doubled the memory footprint of the map. Now we use a compressed set so the second element uses no memory at all. This required some surgery on DenseMap as all accesses to the bucket now have to go through methods; this should have no impact on the behavior of DenseMap though. The new default bucket type for DenseMap is a slightly extended std::pair as we expose it through DenseMap's iterator and don't want to break any existing users. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223588 91177308-0d34-0410-b5e6-96231b3b80d8
