This patch retires runtime.js:
- Removes some dead code from runtime.js (ToPositiveInteger, ToIndex),
- Moves Array.prototype initialization to prologue.js
- Moves SpeciesConstructor to the only file that calls it (typedarray.js)
- Renames the remainder to reflect its only inhabitants ({Max,Min}Simple)

- Introduce new struct AsyncGeneratorRequest, which holds
information pertinent to resuming execution of an
AsyncGenerator, such as the Promise associated with the async
generator request. It is intended to be used as a singly
linked list, and holds a pointer to the next item in te queue.
- Introduce JSAsyncGeneratorObject (subclass of
JSGeneratorObject), which includes several new internal fields
(`queue` which contains a singly linked list of
AsyncGeneratorRequest objects, and `await_input` which
contains the sent value from an Await expression (This is
necessary to prevent function.sent (used by yield*) from
having the sent value observably overwritten during
execution).
- Modify SuspendGenerator to accept a set of Flags, which
indicate whether the suspend is for a Yield or Await, and
whether it takes place on an async generator or ES6
generator.
- Introduce interpreter intrinsics and TF intrinsic lowering for
accessing the await input of an async generator
- Modify the JSGeneratorStore operator to understand whether or
not it's suspending for a normal yield, or an AsyncGenerator
Await. This ensures appropriate registers are stored.
- Add versions of ResumeGeneratorTrampoline which store the
input value in a different field depending on wether it's an
AsyncGenerator Await resume, or an ordinary resume. Also modifies
whether debug code will assert that the generator object is a
JSGeneratorObject or a JSAsyncGeneratorObject depending on the
resume type.

This is basically the minimum viable signal handler for Wasm bounds checks.
It includes the TLS check and the fine grained instructions checks. These
two checks provide most of the safety for the signal handler. Future CLs will
add code range and data range checks for more robustness.
The trap handling code and data structures are all in src/trap-handler, with
the code that actually runs in the signal handler confined to
src/trap-handler/signal-handler.cc.
This changes adds a new V8 API that the embedder should call from a signal
handler that will give V8 the chance to handle the fault first. For hosts that
do not want to implement their own signal handler, we include the option to
install a simple one. This simple handler is also used for the tests.
When a Wasm module is instantiated, information about each function is passed
to the trap handler, which is used to classify faults. These are removed during
the instance finalizer.
Several future enhancements are planned before turning this on by default.
Obviously, the additional checks will be added to MaybeHandleFault. We are
also planning to add a two-level CodeObjectData table that is grouped by
isolates to make cleanup easier and also reduce potential for contending on
a single data structure.
