[clang-check][syntax] Crash in setRole: Assertion `N->getRole() == NodeRole::Detached' failed.

This input is generated by a fuzzer.
Seems to be valid?
Maybe related to #207599

```cxx
static union {
int x;
};
auto test2() -> char(&)[__builtin_omp_required_simd_align(decltype(x))];
```

```
clang-check --tokens-dump example.cpp -- -xc++ -std=c++23
```

Reproduce the crash with clang-check --tokens-dump example.cpp -- -xc++ -std=c++23, then inspect clang/lib/Tooling/Syntax/BuildTree.cpp around setRole at line 556 and the MemberExpr traversal shown in the stack trace. Done means the supplied input no longer triggers the assertion while syntax-tree construction completes normally.
