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.
