Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`. Current number of unresolved compiler crashers: 97 (5282 resolved) Assertion failure in [`include/swift/AST/Type.h (line 288)`](https://github.com/apple/swift/blob/master/include/swift/AST/Type.h#L288): ``` Assertion `isActuallyCanonicalOrNull() && "Forming a CanType out of a non-canonical type!"' failed.
