compiler: handle set-and-use-temp in nilcheck code
Change the code in Unary_expression::do_get_backend that introduces
explicit nil checks for dereference operations to special case
set-and-use-temporary expressions. For this case it is better to
generate an explicit reference of the temp in the final conditional
(avoids introducing tree sharing).
