History
Dan Gohman ad7321f58a Teach LSR to optimize away SMAX operations for tripcounts in common 
cases.  See the comment above OptimizeSMax for the full story, and
the testcase for an example. This cancels out a pessimization
commonly attributed to indvars, and will allow us to lift some of
the artificial throttles in indvars, rather than add new ones.
