Remove an over-eager assertion when setting the value witness table for an archetype.
Remove an over-eager assertion when setting the value witness table for an archetype.

Just because we only want the value witness table for an archetype
doesn't mean that the archetype can't have any other requirements; we
just end up ignoring those requirements. Fixes <rdar://problem/13817115>.
