    rs6000: Handle unresolved overloaded builtin [PR105485]

    PR105485 exposes that new builtin function framework doesn't handle
    unresolved overloaded builtin function well.  With new builtin
    function support, we don't have builtin info for any overloaded
    rs6000_gen_builtins enum, since they are expected to be resolved to
    one specific instance.  So when function rs6000_gimple_fold_builtin
    faces one unresolved overloaded builtin, the access for builtin info
    becomes out of bound and gets ICE then.

    We should not try to fold one unresolved overloaded builtin there
    and as the previous support we should emit one error message during
    expansion phase like "unresolved overload for builtin ...".

            PR target/105485

    gcc/ChangeLog:

            * config/rs6000/rs6000-builtin.cc (rs6000_gimple_fold_builtin): Add
            the handling for unresolved overloaded builtin function.
            (rs6000_expand_builtin): Likewise.

    gcc/testsuite/ChangeLog:

            * g++.target/powerpc/pr105485.C: New test.
