Devang Patel 453d401a51 Add dominance check for the instruction being hoisted. 
For example, MachineLICM should not hoist a load that is not guaranteed to be executed.

Dan Gohman ed2b005842 Tweak IVUsers' concept of "interesting" to exclude add recurrences 
where the step value is an induction variable from an outer loop, to
avoid trouble trying to re-expand such expressions. This effectively
hides such expressions from indvars and lsr, which prevents them
from getting into trouble.
