The primary goal here is to make the type node hierarchy available to other tblgen backends, although it should also make it easier to generate more selective x-macros in the future. Because tblgen doesn't seem to allow backends to preserve the source order of defs, this is not NFC because it significantly re-orders IDs. I've fixed the one (fortunately obvious) place where we relied on the old order. Unfortunately, I wasn't able to share code with the existing AST-node x-macro generators because the x-macro schema we use for types is different in a number of ways. The main loss is that subclasses aren't ordered together, which doesn't seem important for types because the hierarchy is generally very shallow with little clustering. llvm-svn: 373407
