closes #17392 r? @nikomatsakis Kind of a first draft because I'm not sure if this is the right approach. I believe the general idea of giving an error rather than an ICE in obligation_for_builtin_bound is right, but not sure about returning an Option, etc. Also, could probably have a better error message.
