`Self` in where clauses may not be object safe This is virtually certain to cause regressions, needs crater. In #50781 it was discovered that our object safety rules are not sound because we allow `Self` in where clauses without restrain. This PR is a direct fix to the rules so that we disallow methods with unsound where clauses. This currently uses hard error to measure impact, but we will want to downgrade it to a future compat error. Fixes #50781. r? @nikomatsakis 2018-05-22 10:09:35 -05:00			`\|`
