[swiftc (46 vs. 5433)] Add crasher in swift::TypeBase::getCanonicalType(...)
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.
Current number of unresolved compiler crashers: 46 (5433 resolved)
/cc @lattner - just wanted to let you know that this crasher caused an assertion failure for the assertion `Result && "Case not implemented!"` added on 2011-03-22 by you in commit fd2bf74f :-)
Assertion failure in [`lib/AST/Type.cpp (line 1299)`](6267f47959/lib/AST/Type.cpp (L1299)):
```
Assertion `Result && "Case not implemented!"' failed.
When executing: swift::CanType swift::TypeBase::getCanonicalType()
```
Assertion context:
```c++
}
}
// Cache the canonical type for future queries.
assert(Result && "Case not implemented!");
CanonicalType = Result;
return CanType(Result);
}
```
