Add test case for crash triggered in `swift::TypeChecker::checkInheritanceClause(...)`. Current number of unresolved compiler crashers: 54 (5162 resolved) Assertion failure in [`lib/AST/GenericEnvironment.cpp (line 58)`](https://github.com/apple/swift/blob/master/lib/AST/GenericEnvironment.cpp#L58): ``` Assertion `!type->hasArchetype() && "not fully substituted"' failed.
