openmp: Make finalize_task_copyfn order reproduceable [PR104517]
The following testcase fails -fcompare-debug, because finalize_task_copyfn
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.cc (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.
* gcc.dg/gomp/pr104517.c: New test.
