storage/innobase/handler/ha_innodb.cc:
  Remove redundant assignment to thd_to_trx(thd); trx is
  declared as a reference to thd_to_trx(thd) at the top
  of the function, so this assignment isn't useful.
storage/innobase/include/trx0trx.h:
  Remove two unused members from struct trx_struct.  allow_duplicates
  and replace_duplicates are not used; a single duplicates member is
  used instead to represent both flags.
