IR: Don't drop MDNode uniquing on null operands Now that `LLVMContextImpl` can call `MDNode::dropAllReferences()` to prevent teardown madness, stop dropping uniquing just because an operand drops to null. Part of PR21532. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225223 91177308-0d34-0410-b5e6-96231b3b80d8
