BEFORE RESOLVE

Post-parse query rewrite plugin depends on obtained parsed queries in
normalized form using SELECT_LEX::print.  However, only resolved hints
are normally included in this print.  Since, query rewrite plugin only
parses and does not resolve queries, table and index level hints are
not included in the normalized form.  This may cause false matches
between patterns and incoming queries with different hints.

The solution is to add query_type as parameter to Opt_hints::print()
like many other print functions already have.  If query_type is
QT_NORMALIZED_FORMAT, un-resolved hints will also be printed.
