(gfc_conv_expr): Finalize structure constructors for F2003 and
F2008. Warn that this feature was deleted in F2018 and, unlike
array constructors, is not default. Add array constructor
finalblock to the post block.
(gfc_trans_scalar_assign): Suppress finalization by setting new
argument in call to gfc_deallocate_alloc_comp_no_caf. Add the
finalization blocks to the main block.
(gfc_trans_arrayfunc_assign): Use gfc_assignment_finalizer_call
and ensure that finalization occurs after the evaluation of the
rhs but using the initial value for the lhs. Finalize rhs
function results using gfc_finalize_tree_expr.

finalization correctly.

(trans_associate_var): Nullify derived allocatable components
and finalize function targets with defined assignment

(trans_allocate): Finalize source expressions, if required,
and set init_expr artificial temporarily to suppress the

* trans.cc (gfc_add_finalizer_call): Do not finalize the
temporaries generated in type assignment with defined
