PR c++/86094 - wrong code with defaulted move ctor.
gcc/c-family/
* c-opts.c (c_common_post_options): Bump the current ABI version to
13. Set warn_abi_version and flag_abi_compat_version to the current
version rather than 0. Fix defaulting flag_abi_compat_version from
warn_abi_version.
gcc/cp/
* class.c (classtype_has_non_deleted_move_ctor): New.
* tree.c (maybe_warn_parm_abi, type_has_nontrivial_copy_init):
Handle v12 breakage.
