Add test case for crash triggered in `swift::constraints::ConstraintSystem::diagnoseFailureForExpr(...)`.
Current number of unresolved compiler crashers: 35 (5154 resolved)
Assertion failure in `llvm/include/llvm/ADT/ArrayRef.h (line 186)`:
```
Assertion `Index < Length && "Invalid index!"' failed.
When executing: const T &llvm::ArrayRef<swift::Expr *>::operator[](size_t) const [T = swift::Expr *]
```
Assertion context:
```
/// @}
/// @name Operator Overloads
/// @{
const T &operator[](size_t Index) const {
assert(Index < Length && "Invalid index!");
return Data[Index];
}
/// @}
/// @name Expensive Operations
```
Stack trace:
```
