[LLVMdev] Optimization opportunity

[Reid Spencer]

Jeff,

I tried the Benchmarks/Olden/power, Benchmarks/OptimizerEval, and
Benchmarks/Ptrdist/ks tests. They all worked with your patches. I
suggest you update your tree :)

The changes also survived all the Feature and Regression tests on Linux.
So, your changes are committed. 

Thanks for the patches!

Reid.
