Erik Eckstein 50c299e0bf LoopInvariantCodeMotion: don't reuse existing instructions in the loop pre-header ...

This is wrong for hoisted load instructions because we don't check for aliasing in the pre-header.
And for side-effect-free instructions it's not really necessary, because that can cleanup CSE afterwards.
