Promise.h Unforgeable version of the JS builtin Promise.all. Takes a HandleValueVector of Promise objects and returns a promise that's resolved with an array of resolution values when all those promises have been resolved, or rejected with the rejection value of the first rejected promise. Asserts that all objects in the `promises` vector are, maybe wrapped, instances of `Promise` or a subclass of `Promise`. 10630
