 If `RegionInferenceContext::check_universal_regions` fails to prove some outlives constraint `'longer_fr: 'shorter_fr`, we try to propagate it in `fn try_propagate_universal_region_error`. Both these universal regions are either local to the closure or an external region.
 
-In case `'longer_fr` is a local universal region, we search for the largest external region `'fr_minus` which is outlived by `'longer_fr`, i.e. `'longer_fr: 'fr_minus`. There may be multiple such regions, we pick the `mutual_immediate_postdominator` in this case; the fixpoint of repeatedly computing the GLB of all GLBs, see [TransitiveRelation::postdom_upper_bound](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_data_structures/transitive_relation/struct.TransitiveRelation.html#method.postdom_upper_bound) for more details.

 If `'fr_minus` exists we require it to outlive all non-local upper bounds of `'shorter_fr`. There will always be at least one non-local upper bound `'static`.
