placeholder under anonymous block
Normally, Prepared_statement object rewrites the query on execution
to replace ?-placeholders with values. The rewritten query may be written
to logs (including binlog) or stored in the query cache.
But for compound statements, the whole block is prepared and executed,
while contained statements are logged individually. So it doesn't make
sense to rewrite the original statement block. Instead, we need to rewrite
every contained statement. SP is already doing it to replace SP variables
with values. Let it rewrite PS parameters too in the same loop.
