Is that right? If so, there's no need for this test, since Vector asserts already. (And I think the code would read more clearly without it, since the current code seems to try to handle the difference, until you look really closely.)

Is that right? I don't believe that I do. The Stackmap::reps() can be left blank, and doing so means that for any child value whose index is beyond bounds of reps(), we assume ValueRep::Any. The idea is that our OSR exit stackmaps will pretty much universally do this, and it saves us some small amount of memory since we don't have to carry around N copies of ValueRep::Any. Hence why this if statement leaves the rep uninitialized if we're out of bounds. The default constructor of ValueRep is ValueRep::Any.

> The default constructor of ValueRep is ValueRep::Any. Aha! I missed that.

I tested performance because I changed BlockInsertionSet. It's fine. 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 (r191908) "Patchpoint" at /Volumes/Data/primary/OpenSource/WebKitBuild/Release/jsc (r191908) Collected 6 samples per benchmark/VM, with 6 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.
