62ca2aa593 * Implement fully general merging of array subscripts on demand! This 
does not handle the initial pointer index case yet though.

8c25c1a641 * Significant rework of DSNode to support arbitrary aliasing due to merging 
* Now all and any bytes of a DSNode can be merged together individually.  This
  is neccesary to support the full generality of C and support aliasing
  correctly.

38f12f932c Do some cleanups to the Type and Constant section to remove latex stuff 
There is still a lot of cleanup and fleshing out required here, but at least
it gets rid of the flagrantly bad parts.

3fec0954e8 Changes to work with Statistics rework 
* Renamed StatisticReporter.h/cpp to Statistic.h/cpp
    * Broke constructor to take two const char * arguments instead of one, so
      that indendation can be taken care of automatically.
    * Sort the list by pass name when printing
    * Make sure to print all statistics as a group, instead of randomly when
      the statistics dtors are called.
    * Updated ProgrammersManual with new semantics.

ef0e95bb42 Hoist the contents of Loops in depth first order in the dominator tree, 
rather than in random order.  This causes LICM to be DRAMATICALLY more
effective. For example, on bzip2.c, it is able to hoist 302 loads and
2380 total instructions, as opposed to 44/338 before.  This  obviously
makes other transformations much more powerful as well!
