`InferCtxt::resolve_regions_and_report_errors` no longer exists

[ada4a]

This method is referred to in https://rustc-dev-guide.rust-lang.org/type-inference.html#solving-region-constraints, but the link is dead. But I'm not sure which method to update this to:

• There is ObligationCtxt::resolve_regions_and_report_errors, which does have the same name, but its description doesn't seem to match up what the dev-guide says. Plus it's a method on ObligationCtxt, whereas all the other functions in the section come from InferCtxt, or at least rustc_infer.
• And then there is InferCtxt::resolve_regions_with_normalize, whose documentation does align with the description in the section much more closely, especially the ICE-when-used-more-than-once part. But its previous name was just resolve_regions (changed in this commit).

I found rust-lang/rust@a19adef, which says ObligationCtxt is the new home of the method.

also noticed the last link in that section does not go where it is intended to... would you care to fix

There you go: #2577
