    testsuite: tree-ssa: fix PR98265 test to use C++14

    This test was previously not being run at all so this wasn't noticed
    until my fix just now.

    The test needs C++14 and it also should use scan-tree-dump, not
    scan-tree-dump-times, as it wasn't passing a count parameter.

            * g++.dg/tree-ssa/pr98265.C: Use -std=c++14.
            Use scan-tree-dump instead of scan-tree-dump-times.
