FDR: Squash buckets of included literals in FDR confirm

- Change the compile of literal matchers to two passes.
 - Reverse the bucket assignment in FDR, bucket with longer literals has
   smaller bucket id.
 - Squash the buckets of included literals and jump to the the program of
   included literals directly from parent literal program without going
   through FDR confirm for included iterals.
