It inlined a GetById.
This, combined with polyvariant Call/Construct inlining, is a 15-16% speed-up on Raytrace.

Here's the combined impact of polyvariant call, construct, and get_by_id inlining, as well as our loosening of the restrictions on recursive inlining. Benchmark report for SunSpider, Octane, Kraken, and AsmBench on oldmac (MacPro4,1). VMs tested: "TipOfTree" at /Volumes/Data/pizlo/cStack/OpenSource/WebKitBuild/Release/jsc (r162775) "Polyvariant" at /Volumes/Data/fromMiniMe/cStack/OpenSource/WebKitBuild/Release/jsc (r162802) 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.
