f40f0a39bd eliminate the ability to remove global nodes from deadNodeElminate... for now. 
This slows stuff down a bit, but it should get much better before it gets any
worse.

fb39933b75 - Add support for an "auxillary" call site list 
- Original call sites are now never modified after construction by the local
  pass.
- DSGraph::cloneInto can now optionally not clone the call sites
- BUDataStructures no longer has a ton of book-keeping info for a broken
  implementation of the TD data structures

8f0a16eac6 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.

6aa0d62cb9 Add support for a top-down propagation pass. 
Each DSGraph now keeps a list of pending callers that have not
been inlined into the function represented by that graph.
It also keeps a copy of the original call nodes before the BU pass
eliminates some of them.

b195911eab * s/method/function 
* BIG CHANGE: The root of the call "graph" is considered to be the external
  node, not the "Root".  This means that users using graph iterators like
  df_begin() will start from the external node.

* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const
  - It now takes one AnalysisUsage object to fill in instead of 3 vectors
    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)

4dd88f6fbf Big changes. Interval*.h is now more or less finalized. IntervalPartition 
is recoded to use IntervalIterators.  IntervalIterators can now maintain
their own memory or let an external entity do it.

Loop depth is a new user of IntervalPartition for calculating the loop
nesting depth of a basic block

TODO: add IntervalPartition capability to split intervals between the looping
portion and the "tail" portion.
