Goes back to clang-6: https://godbolt.org/z/ss7hKK4YK
Generated by fuzzer that randomly adds `consteval` specifier to functions.
Simplified Test:
```c++
template<typename T>
consteval int foo(int i) {
T instance;
return i;
}
using func_type = int(int);
func_type* p = __builtin_addressof(foo);
```
Stack Dump:
```
clang++: /root/llvm-project/llvm/include/llvm/Support/Casting.h:578: decltype(auto) llvm::cast(From*) [with To = clang::OverloadExpr; From = clang::Expr]: Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' 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.
