Replace the open-coded VMA_SPECIAL_FLAGS check in the VMA merge logic with two new functions vma_flags_can_merge() and vma_can_merge() and update the merge logic to use the former. This abstracts the check and expresses it in terms of the desired behaviour rather than an arbitrary and confusing VMA flag. This also lays the groundwork for making further improvements in VMA flag usage. Also update the userland VMA tests to reflect the change. No functional change intended.

I'd have called it "vma_mergable" etc, because "can_merge" makes me imply a "with what". Acked-by: David Hildenbrand (Arm) <david@kernel.org> -- Cheers, David
