ToString of a Proxied function should not throw Without --harmony-function-tostring, anything other than a JSFunction or JSBoundFunction throw when Function.prototype.toString is called on them. But with the toString revision, anything callable allows toString (and for non-Functions returns the good old "function () { [native code] }" string).

Add capability of throwing values in WASM This is a second attempt at landing CL 644866 which was reverted by CL 667019. Extends the current implementation of WASM exceptions to be able to throw exceptions with values (not just tags). A JS typed (uint_16) array is used to hold the thrown values. This allows all WASM types to be stored (i32, i64, f32, and f64) as well as be inspected in JS. The previous CL was reverted because the WASM compiler made calls to run time functions with tagged objects, which must not be done. To fix this, all run time calls use the thread-level isolate to hold the exception being processed.

[async-await] Eliminate throwaway promise in async functions. The ES2017 specification contains a so-called "throwaway" promise that is used to specify the behavior of await in terms of PerformPromiseThen, but it's actually not necessary and never exposed to user code. In addition to that, hooking up the promise in await required a context (to refer to the generator object) and two closures for the reject/fulfill handling, which would resume the generator corresponding to the async function. That meant, we had to allocate 4 additional objects for every await. Instead of using a JSPromise plus the callbacks, this CL adds logic to allow PromiseReaction and PromiseReactionJobTask to carry arbitrary payloads and Code handlers. We use this for await to avoid the additional 4 objects mentioned above, and instead just have simple Code handlers that resume the generator (for the async function), either by throwing (in case of a rejection) or by resuming normally (in case of fulfillment). For this to work properly the JSGeneratorObject has to have a link to the outer promise returned by the async function, so that the catch prediction can still figure out what to do in case of promise rejection. This is done by adding a new generator_outer_promise_symbol when the debugger is active, which refers from the generator to the outer promise. With this change the doxbee-async-es2017-native test goes from around 100.54ms to around 82.45ms, which corresponds to a ~18% reduction in execution time.

interpreter: make interpreted frames distinguishable in the native stack Before Turbofan/Ignition it was possible to use external profilers to sample running V8/Node.js processes and generate reports/FlameGraphs from that. It's still possible to do so, but non-optimized JavaScript functions appear in the stack as InterpreterEntryTrampoline. This commit adds a runtime flag which makes interpreted frames visible on the process' native stack as distinguishable functions, making the sampled data gathered by external profilers such as Linux perf and DTrace more useful.
