(Install_Body): In the presence of actuals that incomplete types
from a limited view, the instance body cannot be placed after
the declaration because full views have not been seen yet. Any
use of the non-limited views in the instance body requires
the presence of a regular with_clause in the enclosing unit,
and will fail if this with_clause is missing. We place the
instance body at the beginning of the enclosing body, which is
the unit being compiled, and ensure that freeze nodes for the
full views of the incomplete types appear before the instance.
