C/C++ testcase, compile with -fopenmp

The following code fails with an ABORT for the alignment check in the target
region as there is no 'omp_alloc' added for the privatized variables
(private/firstprivate).

It works in the parallel region.

See testcase.

For dynamic allocators, it depends on the WIP patch:
  https://gcc.gnu.org/pipermail/gcc-patches/2023-November/637415.html
but that should be a rather independent issue.

Found while working on PR c++/110347 =E2=80=93 the being created patch cont=
ains for
that PR contains an #if 0 testcase, which shall be enabled once this PR is
fixed.=
