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.

ba12c23ca7 Including the symbol table in the FindUsedTypes analysis was the WRONG way 
to fix test/Regression/CBackend/2003-10-23-UnusedType.ll.  This completely

50b5d71cb7 Make use of "external" depth-first iterators to avoid revisiting nodes 
multiple times.  This reduces the time to construct post-dominance sets a LOT.
For example, optimizing perlbmk goes from taking 12.9894s to 1.4074s.
