Implement a demangleable strong ownership symbol mangling. * The original module symbol mangling scheme turned out to be undemangleable. * The hoped-for C++17 compatibility of weak ownership turns out to be fragile * C++20 now has better ways of controlling C++17 compatibility The issue is captured on the ABI list at: https://github.com/itanium-cxx-abi/cxx-abi/issues/134 GCC implements this new mangling. The old mangling is unceremoniously dropped. No backwards compatibility, no deprectated old-mangling flag. It was always labelled experimental. (Old and new manglings cannot be confused.)
