[PATCH] Improve data-dependency memory barrier example in documentation

In the memory barrier document, improve the example of the data dependency
barrier situation by:

 (1) showing the initial values of the variables involved; and

 (2) repeating the instruction sequence description, this time with the data
     dependency barrier actually shown to make it clear what the revised
     sequence actually is.
