This gives us better leak detection messages, like `Value` has. This also has the side effect of papering over a problem where `MachineInstr`s are added as garbage to the leak detector and then deleted without being removed. If `MDNode::getTemporary()` allocates an `MDNodeFwdDecl` in the same spot, the leak detector asserts. By separating `MDNode`s into their own container we lose that assertion. Since `MachineInstr` is required to have a trivial destructor, its usage of `LeakDetector` at all is pretty suspect. I'll be sending a patch soon to strip that out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224060 91177308-0d34-0410-b5e6-96231b3b80d8
