* gcc-interface/utils.c (can_fold_for_view_convert_p): New predicate.
(unchecked_convert): Use it to disable problematic folding with
VIEW_CONVERT_EXPR in the general case. Always disable it for the
special VIEW_CONVERT_EXPR built for integral types and cope with
its addressability issues by preserving the first conversion.

inlined external functions if they contain a nested function not
declared inline.

* gcc-interface/decl.c (gnat_to_gnu_param): Fix formatting, simplify
and adjust for above renaming.
* gcc-interface/utils.c (convert_vms_descriptor): Likewise. Add new
gnu_expr_alt_type parameter. Convert the expression to it instead
of changing its type in place.

* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Constant>: Remove dead
code. Do not get full definition of deferred constants with address
clause for a use. Do not ignore deferred constant definitions with
address clause. Ignore constant definitions already marked with the
error node.
<object>: Remove obsolete comment. For a deferred constant with
address clause, get the initializer from the full view.
* gcc-interface/trans.c (gnat_to_gnu) <N_Attribute_Definition_Clause>:
Rework and remove obsolete comment.
<N_Object_Declaration>: For a deferred constant with address clause,
mark the full view with the error node.

formatting nits.
