As part of PR22235, introduce `DwarfNode` and `GenericDwarfNode`. The former is a metadata node with a DWARF tag. The latter matches our current (generic) schema of a header with string (and stringified integer) data and an arbitrary number of operands. This doesn't move it into place yet; that change will require a large number of testcase updates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226529 91177308-0d34-0410-b5e6-96231b3b80d8
