e03f32bcc2 * Implement fully general merging of array subscripts on demand! This
does not handle the initial pointer index case yet though.

9cfb358fa4 When printing DS nodes, print the mergemap index as well to allow easier
debugging of merging process.

7b7200c4ea * 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.

e68bf61f6f 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.

952eaee239 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!

d1cf1b458a Fix cwriter to not output FP constants in ascii, output them in hex instead.
This fixes a number of FP precision problems, making the output of the
power benchmark closer to the right answer.

Unfortunately, this only addresses FP constants used directly in functions.
Constants referred to by global constants (such as an array of FP values)
aren't helped by this.  Until this happens power won't work.

a6299345ee * Add capability to recognize alias properties of the following common cases:
- A[c1] cannot alias A[c2] where constants c1 != c2
  - A[i] cannot alias B[j] if A & B are provably different arrays

This should help out array based codes.  For example, from bzip2 from spec,
3 additional loads can be GCSE'd, and _21_ additional loads can be LICMd due
to this change.

In a test example from the Spec GAP benchmark (vecffe.c), this change allows
_52_ additional loads to be GCSE'd and _224_ additional LICM'd loads.

Not bad for such a simple change.  Other testcases show no change at all
because they just don't use arrays.  Not too suprising there.
