commit e759bc64eb5c5eed4f75677ad67246797d486460
Author: Ryan Mack

Bugfix for 53290, fast unique index creation fails on duplicate null values
Summary:
Bug in the fast index creation code incorrectly considers null
values to be duplicates during block merging. Innodb policy is that
multiple null values are allowed in a unique index. Null duplicates
were correctly ignored while sorting individual blocks and with slow
index creation.
Test Plan:
mtr, including new test, load dbs using deferred index creation
