    c++: handle _FloatNN redeclaration like bool [PR107128]

    It's been inconvenient to compile testcases preprocessed with GCC 12 or
    earlier because they break on

      typedef __float128 _Float128;

    We already had code for handling this with bool and wchar_t, it just ne=
eds
    to be extended to _FloatNN as well.

            PR c++/107128

    gcc/cp/ChangeLog:

            * parser.cc (cp_parser_set_decl_spec_type): Use
            redefined_builtin_type for extended_float_type_p.

    gcc/testsuite/ChangeLog:

            * g++.dg/warn/pragma-system_header6.h: New test.
            * g++.dg/warn/pragma-system_header6.C: New test.=
