Fix REINDEX CONCURRENTLY of partitions

Browse Source 
In case of a partition index, when swapping the old and new index, we
also need to attach the new index as a partition and detach the old
one.  Also, to handle partition indexes, we not only need to change
dependencies referencing the index, but also dependencies of the index
referencing something else.  The previous code did this only
specifically for a constraint, but we also need to do this for
partitioned indexes.  So instead write a generic function that does it
for all dependencies.
