[PATCH] D22959: MachineLoopInfo: add methods findLoopPreheader and getExitingBlock

[Sjoerd Meijer via llvm-commits]

I've added a second argument SpeculativePreheader to function findLoopPreheader. This allowed more refactoring in the Hexagon backend as we can don't need a local implementation of that function anymore, but just a call to the one in MachineLoopInfo.
