	PR fortran/34820
	* trans-expr.c (gfc_conv_function_call): Remove all code to
	deallocate intent out derived types with allocatable
	components.
	(gfc_trans_assignment_1): An assignment from a scalar to an
	array of derived types with allocatable components, requires
	a deep copy to each array element and deallocation of the
	converted rhs expression afterwards.
	* trans-array.c : Minor whitespace.
	* trans-decl.c (init_intent_out_dt): Add code to deallocate
	allocatable components of derived types with intent out.
	(generate_local_decl): If these types are unused, set them
	referenced anyway but allow the uninitialized warning.

	PR fortran/34143
	* trans-expr.c (gfc_trans_subcomponent_assign): If a conversion
	expression has a null data pointer argument, nullify the
	allocatable component.

	PR fortran/32795
	* trans-expr.c (gfc_trans_subcomponent_assign): Only nullify
	the data pointer if the source is not a variable.
