Like a big dummy, I completely skipped running this test locally and
forgot it would need check lines. *sigh*, Looks like SOMEONE has a case
of the Mondays!
Anyway, this patch fixes it by adding the proper verify lines.
As reported, OpenACC's variable declaration handling was assuming some
semblence of legality in the example, so it didn't properly handle an
error case. This patch fixes its assumptions so that we don't crash.
Fixes#154008
