IR: Add specialized debug info metadata nodes
Add specialized debug info metadata nodes that match the `DIDescriptor` wrappers (used by `DIBuilder`) closely. Assembly and bitcode support to follow soon (it'll mostly just be obvious), but this sketches in today's schema. This is the first big commit (well, the only *big* one aside from the testcase changes that'll come when I move this into place) for PR22464. I've marked a bunch of obvious changes as `TODO`s in the source; I plan to make those changes promptly after this hierarchy is moved underneath `DIDescriptor`, but for now I'm aiming mostly to match the status quo. llvm-svn: 228640
