[PATCH] Add straight-line strength reduction to LLVM

[Andrew Trick]

I don't like piggybacking on the scheduling mode. When a target selects the scheduler it doesn't expect to get different IR out of the optimizer. Don't surprise users.

It would be fine to add a separate hook for this pass. But I don't think it's an issue until the pass goes into the standard pipeline.
