Introduce another Reset() method in BumpPtrAllocator that calls a destructor
...
on all objects it has allocated, if they are all of the same size and alignment.
Use this to destruct all VNInfos allocated in LiveIntervalAnalysis (PR6653).
valnos is not reliable for this purpose, as seen in r99400
(which still leaked, and sometimes caused double frees).

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.
