    c++: Avoid duplicate diagnostic calling unavailable function [PR109177]

    As the PR shows, we currently emit duplicate diagnostics for calls to
    functions marked with __attribute__((unavailable)). This patch fixes
    that.

    gcc/cp/ChangeLog:

            PR c++/109177
            * call.cc (build_over_call): Use make_temp_override to suppress
            both unavailable and deprecated warnings when calling
            build_addr_func.

    gcc/testsuite/ChangeLog:

            PR c++/109177
            * g++.dg/ext/pr109177.C: New test.
