    libstdc++: Fix name clash with _Cosh in QNX headers [PR 95592]

    This replaces unqualified names like _Cosh with struct std::_Cosh to
    ensure there is no ambiguity with other entities with the same name.

    libstdc++-v3/ChangeLog:

            PR libstdc++/95592
            * include/bits/valarray_after.h (_DEFINE_EXPR_UNARY_OPERATOR)
            (_DEFINE_EXPR_BINARY_OPERATOR, _DEFINE_EXPR_BINARY_FUNCTION):
            Use elaborated-type-specifier and qualified-id to avoid
            ambiguities with QNX system headers.
            * testsuite/26_numerics/valarray/95592.cc: New test.
