This change implements a simple data-flow analysis pass over captured objects to the existing escape analysis. It tracks the state of values in the Hydrogen graph through CapturedObject marker instructions that are used to construct an appropriate translation for the deoptimizer to be able to materialize these objects again. This can be considered a combination of scalar replacement of loads and stores on captured objects and sinking of unused allocations.

Test expectations can now include outcome: FLAKY. The test runner can now run a class of tests (flaky|non-flaky|all). All tests are in the non-flaky class that are not marked as FLAKY. The slash correction for windows is now pulled into the test name method. Currently the progress output on windows contains a mixture of / and \.

If an developer attempts to "subclass" Error by running `MyError.prototype = new Error();`, then the internal v8::Message object that's produced and handed off to `window.onerror` handlers is poorly stringified as "[object Object]". This patch adjusts the stringification process for these objects to include not only native Error objects, but also objects that have Error in their prototype chain, and haven't overwritten Error.toString with some custom variant.

https://codereview.chromium.org/19541010/ The main problem is that if you called Object.getNotifier(obj) on an object, %SetObserved(object) would never get called on it, and thus it would be unobservable (new test added for this). Additionally, Runtime::SetObserved was asserting obj->IsJSObject() which would fail if called on a proxy. It just happens that our existing test always called getNotifier() before Object.observe on proxies, and thus we never previously attempted to transition the map of a proxy. Both issues are now fixed and properly tested.

The start and end time are now measured in microseconds and the type is int64_t. This way it seems more natural as we are going to support submilisecond sampling rate soon.
