Add test case for crash triggered in `swift::SubstitutionMap::lookupConformance`.
Current number of unresolved compiler crashers: 48 (5582 resolved)
Assertion failure in `llvm/include/llvm/ADT/Optional.h (line 138)`:
```
Assertion `hasVal' failed.
When executing: T &&llvm::Optional<swift::ProtocolConformanceRef>::operator*() && [T = swift::ProtocolConformanceRef]
```
Assertion context:
```c++
return hasValue() ? getValue() : std::forward<U>(value);
}
#if LLVM_HAS_RVALUE_REFERENCE_THIS
T&& getValue() && { assert(hasVal); return std::move(*getPointer()); }
T&& operator*() && { assert(hasVal); return std::move(*getPointer()); }
template <typename U>
T getValueOr(U &&value) && {
return hasValue() ? std::move(getValue()) : std::forward<U>(value);
}
```
