Only endloop instructions will conditionally write to a predicate.
When there is an endloop instruction, we preload the values into
new_pred_value.
The only place pred_written is needed is when HEX_DEBUG is on.
We remove the last use of check_for_attrib. However, new uses will be
introduced later in this series, so we mark it with G_GNUC_UNUSED.
