    libstdc++: Add missing parentheses to tests with wrong precedence
    
    These tests are currently evaluated as (err == failbit)|eofbit which is
    not what we want. It should be err == (failbit|eofbit).
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/22_locale/time_get/get/char/3.cc: Add parentheses to
            x == y|z expression.
            * testsuite/22_locale/time_get/get/wchar_t/3.cc: Likewise.
            * testsuite/28_regex/algorithms/regex_match/multiline.cc:
            Likewise.
