      Fix and testcase for BUG#4984 · dde591f2
      unknown authored
       The crash is eliminated but still it is weird/inefficent that ROR-intersection is used when performing updates in empty table.

      This is first cset for WL#1394 "Optimize index merge when all involved index ranges include only values with equal keys"
      The main idea is to exploit the fact that key scans for "key=const" return ordered sequences of rowids.
      
      
      include/my_base.h:
        Added HA_EXTRA_KEYREAD_PRESERVE_FIELDS flag
      include/my_bitmap.h:
        Added a couple of utility functions
      include/my_sys.h:
        Added my_conunt_bits_ushort function
      innobase/include/row0mysql.h:
        Added support for HA_EXTRA_KEYREAD_PRESERVE_FIELDS
      innobase/row/row0sel.c:
        Added support for HA_EXTRA_KEYREAD_PRESERVE_FIELDS
      mysys/my_bit.c:
        Added my_count_bits_ushort function
      mysys/my_bitmap.c:
        Added a couple of utility functions
      sql/ha_berkeley.cc:
        Added cmp_ref rowid comparison function.
      sql/ha_berkeley.h:
        Added cmp_ref rowid comparison function.
      sql/ha_heap.h:
        Added cmp_ref rowid comparison function.
      sql/ha_innodb.cc:
        Added cmp_ref rowid comparison function and support from HA_EXTRA_KEYREAD_PRESERVE_FIELDS
      sql/ha_innodb.h:
        Added cmp_ref rowid comparison function.
      sql/handler.h:
        Added cmp_ref rowid comparison function.
      sql/opt_range.cc:
        Added QUICK_ROR_{INTERSECT,UNION}_SELECT classes and related optimizer code
      sql/opt_range.h:
        Added QUICK_ROR_{INTERSECT,UNION}_SELECT classes
      sql/sql_delete.cc:
        Changed to use new ROWID comparison function
        also always call quick->reset() for quick selects
      sql/sql_select.cc:
        Account for new quick select types
      sql/sql_select.h:
        New, proper rowid ordering/comparison function to be used with Unique class etc.
      sql/sql_test.cc:
        Account for new quick select types
      sql/sql_update.cc:
        Account for new quick select types
