	PR fortran/45305
	* expr.c : Add a prototype for scalarize_intrinsic_call.
	(gfc_simplify_expr): Use scalarize_intrinsic_call for elemental
	intrinsic function calls.
	(scalarize_intrinsic_call): Add 'init_flag' argument. Check if
	the expression or any of the actual argument expressions are
	NULL. Before calling gfc_check_init_expr, check 'init_flag'.
	Only simplify the scalarized expressions if there are no errors
	on the stack.
	(gfc_check_init_expr): Set 'init_flag' true in the call to
	scalarize_intrinsic_call.
