The fillSpeculate*() functions like fillSpeculateCell() should check that current spill format for the virtual register is compatible. If it isn't, then we should force and OSR exit. There are some spot checks in these functions, but we can use the return result from the call to AbstractInterpreter<>::filter() at the top of each function to perform the checks.

Created attachment 250751 [details] Patch Appears neutral overall on performance with a few variations. Notable is that sunspider:string-base64 is reported to be 5% faster, but that could be noise. VMs tested: "Baseline" at /Volumes/Data/src/webkit.baseline/WebKitBuild/Release/jsc (r182806) "143727" at /Volumes/Data/src/webkit/WebKitBuild/Release/jsc (r182806) Collected 4 samples per benchmark/VM, with 4 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.
