These are test-suite benchmarking subset exec_time results for 3 baseline runs (r248957) followed by 3 runs with this patch applied running on an otherwise quiet AMD Jaguar 1.5GHz Ubuntu 14.04 system.

I don't see anything outside of the noise.

This is what I expected given that SimplifyCFG is not currently forming the TCC_Expensive selects that would be undone by this patch. I'll try again with r248439 reverted.
