The main thing is knowing whether the loop pre-header is a place where exiting is OK.

We just have to make a choice to either recognize that as a possibility and document it, or we need to require that Upsilons are canonicalized to the Phi predecessors, and document that. Right now we just leave the question open, hence the FIXME. Also, right now we never run pre-header creation in SSA, so this issue simply doesn't come up. So, we don't know what would happen, if it did come up. Hence, if someone tries to convert the phase to work on SSA (or just invokes the phase in SSA), that FIXME is there to remind you that you have introduced an IR pattern that we previously didn't consider.
This does not appear to have an effect on performance: Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on shakezilla (MacBookPro11,3). VMs tested: "TipOfTree" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc (r189124) "LICMExitOK" at /Volumes/Data/primary/OpenSource/WebKitBuild/Release/jsc (r189124) Collected 7 samples per benchmark/VM, with 7 VM invocations per benchmark. Emitted a call to gc() between sample measurements. Used 1 benchmark iteration per VM invocation for warm-up. Used the jsc-specific preciseTime() function to get microsecond-level timing. Reporting benchmark execution times with 95% confidence intervals in milliseconds.
