2dfc11dc3b Pass to compute various statisics related to DSGraphs.
For now, this just computes the #indirect call sites and
the avg. #callees per indirect call site (actually it prints
both totals and the average is their ratio).

cd37857ad0 Fix two bugs:
* The globals vector was getting broken and unsorted, this caused vortex
   to get badly pessimized
 * Node offset handling was being handled really poorly, and in particular
   we were not merging types with offsets right.  This causes several graphs
   to be non-merged.

928e9c012b * Dramatically rework liveness evaluation.
* Implement the first step of the Globals graph: Deleting nodes from function
  graphs.  In practice, these nodes need to be moved to the globals graph, but
  this will be taken care of later.  Note that the graphs computed right now are
  not strictly correct!

a30663385f * Bottom-Up graphs print the Aux call vector
* Significantly improve DEBUG output
* Aggressively fold calls together if we inlined a graph that provides
  call nodes.
* Add a bailout if the current graph has over 200 call nodes in it, this is
  a really whacky case that should never happen.

1fe76d2385 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.

608bb157f7 Fold arrays down to a single element. This causes huge wins on some benchmarks
for example: 197.parser (64M->14M), 164.gzip (14M->2.7M).  The actual graphs
represented should not change at all.

427b472549 - Add a bunch of checking to make sure that dead nodes are not used after they
are marked DEAD.  This helped track down some bugs
- Fix a bunch of bugs where we were doing work on nodes after they became dead
- Add support for aux function call sites
- Add support for not cloning call sites

7d2624d4f3 Implement a new mergeInGraph method, which basically factors code out of
the BU class.

This will be used by the IPModRef class to do stuff, eventually perhaps the
TD pass will use it also.

Speaking of the TD pass, this also eliminates the self recursive case, which
was broken, and couldn't occur anyway.
