Currently, v8 uses the same flag to collect time for instantiating wasm modules from js asm and wasm. This separates the v8 counter into two separate counters, and then uses the appropriate counter when instantiating a module.

V8 side mechanism for overriding the wasm js APIs. We will use these to: - implement the Chrome-side constraints on module size, and throw with more actionable error messages, while preserving layering. The old mechansms will be deleted once we update the Chrome side with this new mechanism. - implement Chrome-side .compile and .instantiate overrides accepting Response objects. We may want to evolve this mechanism into something more general, not requiring V8 preparation, by replacing the v8-definition with embedder provided definitions. We're currently exploring if we can expand "Extras", for instance. BUG= Review-Url: https://codereview.chromium.org/2773063002 Cr-Commit-Position: refs/heads/master@{#44119}

[runtime] Immediately set the array-index hash in Uint32ToString and convert to string in ForInPrepare This speeds up for/in over arrays. E.g.,: function f(a) { for (let i in a) { if (a[i] != a[i]) print(false); } } var a = new Array(10000000); a.fill(1); f(a); runs 3x faster after the change.

Removes the AstString super-class and makes the two sub-classes stand-alone. That also removes the slightly awkward implementation of a super-class with dynamically dispatched behaviour, except it was manually implemented because virtual function calls were considered expensive.
