Placeholder metadata for operands of distinct MDNodes.
This is a lightweight placeholder for an operand of a distinct node. It's purpose is to help track forward references when creating a distinct node. This allows distinct nodes involved in a cycle to be constructed before their operands without requiring a heavyweight temporary node with full-blown RAUW support.
Each placeholder supports only a single MDNode user. Clients should pass an ID, retrieved via getID(), to indicate the "real" operand that this should be replaced with.
While it would be possible to implement move operators, they would be fairly expensive. Leave them unimplemented to discourage their use (clients can use std::deque, std::list, BumpPtrAllocator, etc.).
