Dan Gohman d632f89596 Make LSR's OptimizeShadowIV ignore induction variables with negative 
strides for now, because it doesn't handle them correctly. This fixes a
miscompile of SingleSource/Benchmarks/Misc-C++/ray.

This problem was usually hidden because indvars transforms such induction
variables into negations of canonical induction variables.
