Propagate whether `MDNode`s are 'distinct' through the other types of IR (assembly and bitcode). This adds the `distinct` keyword to assembly. Currently, no one actually calls `MDNode::getDistinct()`, so these nodes only get created for: - self-references, which are never uniqued, and - nodes whose operands are replaced that hit a uniquing collision. The concept of distinct nodes is still not quite first-class, since distinct-ness doesn't yet survive across `MapMetadata()`. Part of PR22111. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225474 91177308-0d34-0410-b5e6-96231b3b80d8
