179bc7dcb1 Implement a small optimization to handling of GEP's that are equivalent to casts.
This results in substantially reduced collapsing for some testcases

15869aa2c7 All DSGraphs keep a reference to the targetdata they are created with. This is
used to eliminate the hard coded, hacked in, sparc specific, global TargetData.
Changing the TargetData used to actually match the code fixes problems, and
eliminates a crash.

50b5d71cb7 Make use of "external" depth-first iterators to avoid revisiting nodes
