dac0b853e1 Improve speed of Utf8Write by always flattening the string first and 
detecting the ASCII case.  Also rewrite Utf8Length to work on an
unflattened string.  Bug: http://code.google.com/p/v8/issues/detail?id=1665

16ae2551ae Search prototypes for accessor setters if interceptor returns empty value. 
Extract the part of SetPropertyForResult that searches the prototype chain
for accessor setters into a separate function SetPropertyInPrototypes.
Call this function in SetPropertyPostInterceptor.

This should fix both optimized and unoptimized cases because
the cache stub for storing with interceptor calls the runtime system.

bdf6895bb3 Encapsulate element handling into a class keyed on ElementsKind 
Advantage is that it's much easier to add new element types (like FAST_SMI_ELEMENTS), and that handling logic for each element kind is (more) consolidated.

Currently, only GetElementsWithReceiver uses the new encapsulation, but the goal is to move much more element functionality into the class incrementally.

4487f8c050 Revert "Revert "Fix a bug in scope analysis."" 
Reapply r8783 with an additional fix.

Because the preparser and parser do not use the same scope analysis to
determine if a function can be lazily compiled, the parser can have false
positives.  Rather than treating this as a parse error, treat the preparser
as authoritative and eagerly compile the function.

615add8463 Expose APIs for detecting boxed primitives, native errors and Math. 
While implementing structured clone I found that I need support
for detecting and creating objects using the builtin Number, String
and Boolean constructors; this CL adds this support. I also need
to be able to detect entities of "native object type (e.g., Error)",
hence the new IsNativeError() calls.

508b22c436 "Deiceolate" Thread classes. 
Thread class was receiving an isolate parameter by default.
This approact violates the assumption that only VM threads
can have an associated isolate, and can lead to troubles,
because accessing the same isolate from different threads
leads to race conditions.

This was found by investigating mysterious failures of the
CPU profiler layout test on Linux Chromium. As almost all
threads were associated with some isolate, the sampler was
trying to sample them.

As a side effect, we have also fixed the DebuggerAgent test.

Thanks to Vitaly for help in fixing isolates handling!

BEFORE an access control section (e.g. public:, private:) there should be a
blank line (except for the section right after the class declaration).

AFTER an access control section there should be no blank line.
