Clang trunk crashed and goes back to 3.6.

The assertion is same as #22245, but have a different stack dump.
## Program
```cpp
template <class T> int f(T) {
struct MyClass {
static int staticField;
};
int MyClass::staticField = 42;
uintptr_t base = reinterpret_cast<uintptr_t>(&MyClass::staticField);
return 0;
}
int main() { f(0); }
```
## Stack Dump
```bash
<source>:3:16: error: static data member 'staticField' not allowed in local struct 'MyClass'
3 | static int staticField;

<source>:6:3: error: unknown type name 'uintptr_t'
