Summary
Add support for Callee-Saves registers

Reported

Save and restore platform callee save registers. We only do this for 64 bit builds as it isn't needed nor expected to be profitable for 32 bit builds.

Performance results look neutral overall. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on msaboff-pro (MacPro5,1). VMs tested: "Baseline" at /Volumes/Data/src/webkit.baseline/WebKitBuild/Release/JavaScriptCore.framework/Versions/A/Resources/jsc "CalleeSaves" at /Volumes/Data/src/webkit/WebKitBuild/Release/JavaScriptCore.framework/Versions/A/Resources/jsc 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.
