At least some of these regressions might be expected due to my patch (12b8a92e9d04b87ef5d3b4406e6ad86f785dc700).  The compiler has gotten lazier about deriving type metadata pointers.  To the extent that those are necessary for debuggability, we need to figure out some way to reconstruct that information in the debugger; if necessary, we can eagerly project at least the primary type parameters in -Onone -g builds, but I’d like to discuss it (more; we did already talk about this a month or so ago) before we take that step.
