0b178e25c4 remove the instcombine transformations that are inserting nasty 
pointer to int casts that confuse later optimizations.  See PR3351
for details.

This improves but doesn't complete fix 483.xalancbmk because llvm-gcc
does this xform in GCC's "fold" routine as well.  Clang++ will do
better I guess.

48b59ec817 reapply r85085 with a bugfix to avoid infinite looping. 
All of the 'demorgan' related xforms need to use 
dyn_castNotVal, not m_Not.

f2f6ce65b7 Change tests from "opt %s" to "opt < %s" so that opt doesn't see the 
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename.
