I've now pushed something.

This doesn't make the native comp build work, but the errors are
different, and in the cases of IGC_OBJ_FWD assertions I think these
don't have the same cause, at least they don't follow the patterns I've
previously seen in LLDB.

In summary, I think this is an improvement.

Could anyone (of the currently n = 3 people reporting back
(not disappointing because expected) try this?
