6d2f67adb3 Initial support for implementing clonePartiallyInto in terms of cloneReachableSubgraph, though this support is currently disabled.

a72f3a387a Eliminated the CompletedNodes argument to the cloneReachable* methods. This 
map was only used to implement a marginal GlobalsGraph optimization, and it
actually slows the analysis down (due to the overhead of keeping it), so just
eliminate it entirely.

07d45564d0 Start implementing DSGraph::clonePartiallyInto and implement mergeInGraph 
in terms of it.

Though clonePartiallyInto is not cloning partial graphs yet, this change
dramatically speeds up inlining of graphs with many scalars.  For example,
this change speeds up the BU pass on 253.perlbmk from 69s to 36s, because
it avoids iteration over the scalar map, which can get pretty large.

7485243e7a Implement a small optimization to handling of GEP's that are equivalent to casts. 
This results in substantially reduced collapsing for some testcases

a71b07eeca 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.
