Fixed bugs (mostly on sparc) that caused crashes in mysql-test-run

sql/item_sum.cc:
  Fixed alignment problem that caused crases on sparc. (ORDER needs an aligment of 8 as it includes longlongs)
storage/federatedx/ha_federatedx.cc:
  Fixed crash on sparc as 'pos' is not aligned on 4/8.
storage/maria/ma_page.c:
  Removed wrong assert
