[clang][bytecode] crashes with --std=c++20 when typeid is used on consteval-evaluated object #160071
Description
Reproducer:
https://godbolt.org/z/YE9fY3xKv
namespace std {
struct type_info;
};
struct C {};
consteval C fC() { return {}; }
C c = fC();
consteval const std::type_info *ftype_info() { return &typeid(c); }
const std::type_info *T1 = ftype_info();Backtrace:
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
