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

986ec528fd * actually handle constants (especially constantexprs) correctly. 
- This seems to dramatically improve many benchmarks, only slowing down
    gzip significantly.

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.

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.  :)
