The num_tasks computation has long been based on NumberOfAvailableBackgroundThreads() We used to have one background worker per core, stealing cycles from the main thread. I fixed that @ crrev.com/534414. But now this computation is wrong and generates one less task than it should (one per worker but the main thread takes task #0 in practice). Other usage of NumberOfAvailableBackgroundThreads() in V8 seem correct already so this is the only tweak required.

This merely re-uses the same ScopeId as the task. Tracing shows these as a nested layer with the same name. This is not the cleanest way to do this but it makes the trace clearer for a minimal diff.

The perf jit support assumes that if a code object has source position entries, then it has a source file associated with them. However, the WasmToJS wrapper stubs are exceptions to this rule which causes a crash when using `--perf-prof` with asm.js or WASM code.

The `simpleBind` function exposed by V8 Extras was initially added to work around the terrible performance of `Function.prototype.bind` at the time. Nowadays `Function.prototype.bind` is significantly faster and fully optimized by TurboFan, however, so there’s no need for the `simpleBind` helper anymore.

We want to be able to use this from other builtins as well, so move it to somewhere common. Also adds typing and cleans up the coding style to match newer CSA code a bit more. GrowableFixedArray is now a subclass of CodeStubAssembler to make things easier and cleaner. The growing strategy has also been slightly changed so that empty arrays can be produced.

The catch prediction logic got confused when we merged the reactions and result fields of JSPromise, because for settled promises it would start to treat the result as reactions list, leading to a crash most likely or memory corruption in the worst case (only if break on uncaught exception is enabled). We can only inspect reactions when the promise is still in "pending" state.

This adds support for the {i64.const} opcode. Since this makes i64 values show up on the wasm stack, quite some code paths need to handle them. The {CheckSupportedType} method still returns false for kWasmI64, which will be changed in a follow-up CL. That requires more changes since it unlocks more uses of i64, e.g. in loads and stores.

The test required a special runtime function, which did not work in general but only in the context of that one test.

This adds a new isolate wide Promise#then protector, which guards the "then" lookup for all JSPromise instances whose [[Prototype]] is the initial %PromisePrototype%. Thus arbitrary mutations to the Promise.prototype (i.e. monkey-patching other methods or installing new functions) no longer sent you down the slow-path. Use this protector in Promise.prototype.catch and in Promise.resolve. Drive-by-fix: Restructure the resolve logic a bit and avoid the expensive and large SameValue check, which can be turned into a simple reference equal, as the promise in there is known to be a JSPromise anyways.
