Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root

The idea of the fix is that the administrative statements
OPTIMIZE TABLE, REPAIR TABLE and ANALYZE TABLE should not
generate binlog errors if there is no errors on the master.
sql/sql_parse.cc:
No binlog error generated
