    libstdc++: Fix std::type_info::before for ARM [PR103240]

    The r179236 fix for std::type_info::operator=3D=3D should also have been
    applied to std::type_info::before. Otherwise two distinct types can
    compare equivalent due to using a string comparison, when they should do
    a pointer comparison.

    libstdc++-v3/ChangeLog:

            PR libstdc++/103240
            * libsupc++/tinfo2.cc (type_info::before): Use unadjusted name
            to check for the '*' prefix.
            * testsuite/util/testsuite_shared.cc: Add type_info object for
            use in new test.
            * testsuite/18_support/type_info/103240.cc: New test.=
