	PR fortran/58586
	* resolve.c (resolve_symbol): Non-private functions in modules
	with allocatable or pointer components are marked referenced
	now. Furthermore is the default init especially for those
	components now done in gfc_conf_procedure_call preventing
	duplicate code.
	* trans-decl.c (gfc_generate_function_code): Generate a fake
	result decl for functions returning an object with allocatable
	components and initialize them.
	* trans-expr.c (gfc_conv_procedure_call): For value typed trees
	use the tree without indirect ref. And for non-decl trees
	add a temporary variable to prevent evaluating the tree
	multiple times (prevent multiple function evaluations).
	* trans.h: Made gfc_trans_structure_assign () protoype
	available, which is now needed by trans-decl.c:gfc_generate_
	function_code(), too.
