Just like the last handful of patches that did copy, copyin, copyout,
create, etc, this patch has the exact same behavior, except the
entry op is a present, and the exit is delete.

Subject: [PATCH] [OpenACC][CIR] Implement 'present' lowering on local-declare
Just like the last handful of patches that did copy, copyin, copyout,
create, etc, this patch has the exact same behavior, except the
entry op is a present, and the exit is delete.
