[clang] Assertion `T::isKind(*this)' failed when invoking an inherited constructor with [[gnu::stdcall]] attribute

Reproducer:
https://godbolt.org/z/zc67bq5n5
```cpp
struct S {
[[gnu::stdcall]] S(int);
};

struct SS : S {
using S::S;
void foo() { SS(42); }
};
```

Backtrace:
```console
clang++: /root/llvm-project/llvm/tools/clang/include/clang/AST/TypeLoc.h:79: T clang::TypeLoc::castAs() const [with T = clang::FunctionProtoTypeLoc]: Assertion `T::isKind(*this)' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
