The temp_instance is not used but had an enormous performance impact. The instantiation time of the zengarden WebAssembly module improved now from 12 seconds to less than a second.

[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.

Add the --fast-validate-asm option, which directs asm.js code to a new parser + validator + wasm code generator, which is then compiled using WebAssembly. This parser takes advantage of asm.js structure to linearly parse asm.js code, keeping a scope stack + a few additional tables to track varibles.

There was a security issue from allowing WindowProxy to have its prototype mutated in https://bugs.chromium.org/p/chromium/issues/detail?id=399951 . This has since been resolved by making `window`, `location`, and `Object.prototype.__proto__` immutable. This change was fixed in https://bugs.chromium.org/p/v8/issues/detail?id=5149 .

This patch makes Math.random() behave deterministically when a fixed random seed is provided. This is done by re-seeding the random number generator the first time a script requests a random number. Doing this ensures Math.random() returns the same sequence across page loads and across iframes.
