[swiftc (149 vs. 5199)] Add crasher in swift::TypeBase::getCanonicalType(...)
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.
Current number of unresolved compiler crashers: 149 (5199 resolved)
Assertion failure in [`lib/AST/Type.cpp (line 1286)`](https://github.com/apple/swift/blob/master/lib/AST/Type.cpp#L1286):
```
Assertion `Result && "Case not implemented!"' failed.
When executing: swift::CanType swift::TypeBase::getCanonicalType()
```
Assertion context:
```
}
}
// Cache the canonical type for future queries.
assert(Result && "Case not implemented!");
CanonicalType = Result;
return CanType(Result);
}
```
