Fix for bug #31137: Assertion failed: primary_key_no == -1 || primary_key_no == 0,

Browse Source 
file .\ha_innodb.

Problem: if a partial unique key followed by a non-partial one we declare
the second one as a primary key.

Fix: sort non-partial unique keys before partial ones.

  Fix for bug #31137: Assertion failed: primary_key_no == -1 || primary_key_no == 0, 
  file .\ha_innodb.
    - sort unique keys that don't contain partial segments before other keys:
        set HA_KEY_HAS_PART_KEY_SEG flag for such keys in the mysql_prepare_table(),
        use it in the sort_keys();
