Count buffers dirtied due to hints in pgBufferUsage.shared_blks_dirtied.

Previously, such buffers weren't counted, with the possible result thatEXPLAIN (BUFFERS) and pg_stat_statements would understate the truenumber of blocks dirtied by an SQL statement.Back-patch to 9.2, where this counter was introduced.Amit Kapila
