    OpenMP: Unshare expr in context-selector condition [PR121922]

    As the testcase shows, a missing unshare_expr caused that the condition
    was only evaluated once instead of every time when a 'declare variant'
    was resolved.

            PR middle-end/121922

    gcc/ChangeLog:

            * omp-general.cc (omp_dynamic_cond): Use 'unshare_expr' for
            the user condition.

    libgomp/ChangeLog:

            * testsuite/libgomp.c-c++-common/declare-variant-1.c: New test.
