    c++: fix 'unsigned __int128_t' semantics [PR108099]

    My earlier patch for 108099 made us accept this non-standard pattern but
    messed up the semantics, so that e.g. unsigned __int128_t was not a 128=
-bit
    type.

            PR c++/108099

    gcc/cp/ChangeLog:

            * decl.cc (grokdeclarator): Keep typedef_decl for __int128_t.

    gcc/testsuite/ChangeLog:

            * g++.dg/ext/int128-8.C: New test.=
