    Add 'dg-do run' to 'libgomp.fortran/use_device_ptr-optional-3.f90'
[PR94848]

    Fix-up for r279858/commit f760c0c77fe350616da9dbeaea16442b0acfb09c
"Fortran]
    OpenMP/OpenACC =C3=A2 fix more issues with OPTIONAL".

    With offloading enabled, we then saw:

     ... due to:

`A.12.4064'
        [...]

    ..., but after the recent PR94848, PR95551 changes, that problem is now
gone.
