226c503f31 Stop representing scalars as explicit nodes in the graph. Now the only 
nodes in the graph are memory objects, which is very nice.  This also greatly
reduces the size and memory footprint for DSGraphs.  For example, the local
DSGraph for llu went from 65 to 13 nodes with this change.  As a side bonus,
dot seems to lay out the graphs slightly better too.  :)

larger one.

f94d110749 Do not print "NEW FILES AND DIRECTORIES" unless requested separately 
because this is usually such a long list that it makes the output
useless anyway.

Disable checking exit status until we can find something more precise.
The exit status is too coarse-grain to be useful.

cd6a3b2f2c Refactored DSGraph.h: 
* DSGraph.h   contains DSGraph
* DSNode.h    contains DSNode (soon UDSNode and MDSNode)
* DSSupport.h contains DSCallsite, DSTypeRec, and DSNodeHandler

317daff9bf This fixes all kinds of problems with array handling. There are still bugs to 
be fixed, but we are getting much closer now.

    * Make DSNode::TypeRec a full fledged DSTypeRec type.
    * Add methods used to update and access the typerecords elements
    * Add methods to query if and to cause a node to be completely folded
    * DSGraph construction doesn't use the allocation type for anything at all,
      now nodes get their type information based on how they are used.
    * Fixed a bug with global value handling introduced in the last checkin
    * GEP support is now much better, arrays are handled correctly.  The array
      flag is now updated in type records.  There are still cases that are not
      handled yet (we do not detect pessimizations), but getting much closer.

0396c5461e Fix two problems: 
* Load Implementation can cause unaligned memory accesses, which caused
    problems for sparc.
  * cast from pointer to pointer would zero the upper 32 bits of the pointer
    which obviously causes problems on 64 bit hosts.
