Fixed on the trunk.  As I said, there is nothing that can be done for older
versions.

c++, libstdc++: Add typeinfo for _Float{16,32,64,128,32x,64x} and __bf16
types [PR108075]

The following patch adds typeinfos for the extended floating point
types and _Float{32,64}x.

Untested fix.  There is nothing that can be done for GCC 12 though.

Following shows much more types without typeinfo (only _Float128x is fine
because it isn't supported on any target).

#include 

#ifdef __STDCPP_FLOAT16_T__
const std::type_info  = typeid(decltype(0.0f16));
#endif
#ifdef __STDCPP_BFLOAT16_T__
const std::type_info  = typeid(decltype(0.0bf16));
#endif
#ifdef __STDCPP_FLOAT32_T__
const std::type_info  = typeid(decltype(0.0f32));
#endif
#ifdef __STDCPP_FLOAT64_T__
const std::type_info  = typeid(decltype(0.0f64));
#endif
#ifdef __STDCPP_FLOAT128_T__
const std::type_info  = typeid(decltype(0.0f128));
#endif
#ifdef __FLT32X_MAX__
const std::type_info  = typeid(decltype(0.0f32x));
#endif
#ifdef __FLT64X_MAX__
const std::type_info  = typeid(decltype(0.0f64x));
#endif
#ifdef __FLT128X_MAX__
const std::type_info  = typeid(decltype(0.0f128x));
