This commit implements optimizer hints allowing to affect the order
of joining tables:

 - JOIN_FIXED_ORDER similar to existing STRAIGHT_JOIN hint;
 - JOIN_ORDER to apply the specified table order;
 - JOIN_PREFIX to hint what tables should be first in the join;
 - JOIN_SUFFIX to hint what tables should be last in the join.
