A global predicate is not guarnatenteed to outlive all regions. If the predicate involves late-bound regions, then it may fail to outlive other regions (e.g. `for<'b> &'b bool: 'static` does not hold) We now only produce `EvaluatedToOk` when a global predicate has no late-bound regions - in that case, the ony region that can be present in the type is 'static

A global predicate is not guarnatenteed to outlive all regions.
If the predicate involves late-bound regions, then it may fail
to outlive other regions (e.g.
for<'b> &'b bool: 'staticdoes nothold)
We now only produce
EvaluatedToOkwhen a global predicate has nolate-bound regions - in that case, the ony region that can be present
in the type is 'static
