Is this extra complexity worth one saved GetCurrentTimestamp()?

src/backend/access/transam/xact.c is calling GetCurrentTimestamp a
lot already, so I don't really buy the argument it should be avoided
at all cost in pg_stat_statements. Just storing the statement end time
would make this use case much nicer.
