c1b7de86d5 Checkin some major reworks of data structure analysis. This is not done, 
nor does it work very well, but I need to get it checked in before I break
the tree unintentionally.

ends with a struct index.

ef0e95bb42 Hoist the contents of Loops in depth first order in the dominator tree, 
rather than in random order.  This causes LICM to be DRAMATICALLY more
effective. For example, on bzip2.c, it is able to hoist 302 loads and
2380 total instructions, as opposed to 44/338 before.  This  obviously
makes other transformations much more powerful as well!

940f3fa91b Overhaul integer conversions to match C++ ISO standard. 
Don't allow direct FP-to-uint conversion (must be eliminated by preselection).
Address arithmetic for arrays is now entirely 64-bit so no sign-ext needed.
