Set correct cost data in Gather node added by force_parallel_mode.
We were just leaving the cost fields zeroes, which produces obviously bogus
output with force_parallel_mode = on. With force_parallel_mode = regress,
the zeroes are hidden, but I wonder if they wouldn't still confuse add-on
code such as auto_explain.
