1628cec4d7 For PR950:
Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

60a05cc118 Fix Transforms/IndVarsSimplify/2006-03-31-NegativeStride.ll and
PR726 by performing consistent signed division, not consistent unsigned
division when evaluating scev's.  Do not touch udivs.

803513b364 Fix a case where we incorrectly returned hasComputableLoopEvolution for
a ternary commutative expr.  Remove FIXME that does not need to be fixed
(can't happen).
