Currently if you allocate a large array with new Array(large number), you'll get an ArrayStorage array, which is slower than a Contiguous array. That threshold is very low - around 10000. We should dramatically lift the threshold.

Performance results: Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on dethklok (MacBookPro9,1). VMs tested: "TipOfTree" at /Volumes/Data/pizlo/secondary/OpenSource/WebKitBuild/Release/jsc (r183718) "MoreContiguous" at /Volumes/Data/pizlo/quartary/OpenSource/WebKitBuild/Release/jsc (r183721) 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.

It appears that this broke mozilla-tests.yaml/js1_5/Array/regress-157652.js on iOS. That test now appears to be flakey. Here are some of the test outputs since <http://trac.webkit.org/changeset/183787>. Note that these are 64 bit results, but the failure is seen on 32 bit systems as well.
