This relands r250831 after some fixes to shrink the ParentMap overall with one addtional tweak: nodes with pointer identity (e.g. Decl* and friends) can be store more efficiently so I put them in a separate map. All other nodes (so far only TypeLoc and NNSLoc) go in a different map keyed on DynTypedNode. This further uglifies the code but significantly reduces memory overhead. Overall this change still make ParentMap significantly larger but it's nowhere as bad as before. I see about 25 MB over baseline (pre-r251008) on X86ISelLowering.cpp. If this becomes an issue we could consider splitting the maps further as DynTypedNode is still larger (32 bytes) than a single TypeLoc (16 bytes) but I didn't want to introduce even more complexity now.
