    openmp: Make finalize_task_copyfn order reproduceable [PR104517]

    The following testcase fails -fcompare-debug, because finalize_task_cop=
yfn
    was invoked from splay tree destruction, whose order can in some cases
    depend on -g/-g0.  The fix is to queue the task stmts that need copyfn
    in a vector and run finalize_task_copyfn on elements of that vector.

            * omp-low.c (task_cpyfns): New variable.
            (delete_omp_context): Don't call finalize_task_copyfn from here.
            (create_task_copyfn): Push task_stmt into task_cpyfns.
            (execute_lower_omp): Call finalize_task_copyfn here on entries =
from
            task_cpyfns vector and release the vector.
