  SVN rev 196336 on 2009-08-17 16:33:53Z by attilio
  
  MFC r196334:
  
  * Change the scope of the ASSERT_ATOMIC_LOAD() from a generic check to
    a pointer-fetching specific operation check. Consequently, rename the
    operation ASSERT_ATOMIC_LOAD_PTR().
  * Fix the implementation of ASSERT_ATOMIC_LOAD_PTR() by checking
    directly alignment on the word boundry, for all the given specific
    architectures. That's a bit too strict for some common case, but it
    assures safety.
  * Add a comment explaining the scope of the macro
  * Add a new stub in the lockmgr specific implementation
