#1 is to unconditionally strip constantpointerrefs out of
instruction operands where they are absolutely pointless and inhibit
optimization.  GRRR!

#2 is to implement InstCombine/getelementptr_const.ll

extractor has extracted hundreds of loops from the SPEC benchmarks without crashing
and without misoptimizing the programs.

This testcase could be reduced substantially more by hand, but I don't have time
to work on it right now.

folding load instructions into other instructions across free instruction
boundaries.  Perhaps this will also fix the other strange failures?

With this fix we now successfully extract all 149 loops from 256.bzip2 without
crashing or miscompiling the program!

extracted all 63 loops for Olden/bh without crashing and without
miscompiling the program!!!

1. Names were not put on the new arguments created (ok, this just helps sanity :)
2. Fix outgoing pointer values
3. Do not insert stores for values that had not been computed
4. Fix some wierd problems with the outset calculation

This fixes CodeExtractor/2004-03-14-DominanceProblem.ll, making the extractor
work on at least one simple case!
