  BUG#25951 - ignore/use index does not work with fulltext
  
  IGNORE/USE/FORCE INDEX hints were honored when choosing FULLTEXT
  index.
  
  With this fix these hints are ignored. For regular indexes we may
  perform table scan instead of index lookup when IGNORE INDEX was
  specified. We cannot do this for FULLTEXT in NLQ mode.

    IGNOR/USE/FORCE INDEX hints should not be honored when choosing FULLTEXT
    index.
    
    Use proper bitmap, that is not modified by IGNORE/USE/FORCE INDEX hints.
