Add the ability to "intern" FoldingSetNodeID data into a BumpPtrAllocator-allocated region to allow it to be stored in a more compact form and to avoid the need for a non-trivial destructor call. Use this new mechanism in ScalarEvolution instead of FastFoldingSetNode to avoid leaking memory in the case where a FoldingSetNodeID uses heap storage, and to reduce overall memory usage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98829 91177308-0d34-0410-b5e6-96231b3b80d8
