--- Description ---
This allows to perform GCSE on various derived properties, e.g. NewArray and
NewArrayBuffer operations can now def() their length and elements.
However benchmark times are showing a slight slowdown in most cases, possibly
due to LazyNode having twice the size of a Node*, so I am not sure this is
worth pursuing.


VMs tested:
"r184563" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc
"LazyNode" at
/Volumes/Data/secondary/OpenSource/WebKitBuild/LazyNode/Release/jsc

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.
