263dce9b57 [js] Remove CORE JS Natives (prologue.js), port extra utils to C++/Torque
- Removes the last `CORE` JS native script: `prologue.js`.
- Removes build step and bootstrapping associated with building/loading `CORE` JS natives.
- Removes `natives_utils_object` from context.
- Deprecates `--expose-natives-as` flag.
- Ports extra utils functions to C++ (`uncurryThis`) or Torque
  (`createPrivateSymbol`, `markPromiseAsHandled`, and `promiseState`).
- Move extra utils constants initialization into bootstrapper
  (`kPROMISE_PENDING`, `kPROMISE_FULFILLED`, `kPROMISE_REJECTED`).
- Removes unused extra utils functions `log` and `logStackTrace`.

Drive-by: Added test coverage for Array#includes being an unscopeable.

640d3adf5f [builtins] Remove InternalArray and reduce InternalPackedArray constructors.
InternalPackedArray now only has one constructor variant that expects no
arguments (Chrome's only usage of InternalPackedArray). As such, these TFC
builtins are no longer used and were removed:
- InternalArrayNoArgumentConstructor_Holey
- InternalArraySingleArgumentConstructor_Packed
- InternalArraySingleArgumentConstructor_Holey

On x64.release, this reduces builtins size by ~1.2KB.

13ca9a0fd1 [turbofan] Properly optimize calls to promise extras.
Add TurboFan inlining support for the following V8 Extras:

 - v8.createPromise
 - v8.rejectPromise
 - v8.resolvePromise

These are used by the streams implementation in Chrome currently, and
were previously not inlined into TurboFan, although TurboFan already
had all the necessary functionality (namely the JSCreatePromise,
JSRejectPromise and JSResolvePromise operators). We might eventually
want to use these functions in Node core as well (at least short-term
for Node 10), to replace the C++ internal API functions with the same
name that are currently being used by parts of Node core.

For this to work, the rejectPromise and resolvePromise builtins had
to be moved back to CSA, as for JavaScript builtins we still have the
policy that the optimizing compiler must not inline them. But that's
straight-forward since the CSA has all the necessary functionality
available anyways.

fefee7dc1b [v8-extras] Remove simpleBind
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.

0d25fee308 Add isPromise V8 extras util
This is used by streams in
https://streams.spec.whatwg.org/commit-snapshots/1375e266b2fe8246bd95cb9d8a49876ba9359dc9/#rs-pipe-through

This also fixes an omission in a6e635d692
that did not properly update the
%OptimizeObjectForAddingMultipleProperties call in prologue.js.

This will allow V8 extra consumers to track promise state without
using a side-table. This is used by streams as of

a0e3a8ee89 [promises] Remove unneeded PromiseCreate function from promise.js
This function was only needed for extrasUtils. Since it was simply
calling a builtin function, just expose that builtin instead. This
requires an arguments adapter frame for the builtin. As a drive-by
fix, also added an arguments adapter for the extrasUtils.resolvePromise
(and a regression test).

Other cleanup: removed unused native context slot for PROMISE_SET_AND_CREATE.

8f8457d2a4 Add methods to extras' InternalPackedArray
https://codereview.chromium.org/1343113003 introduced a separate InternalPackedArray constructor to the extras utils object, distinct from the one used by natives. However, it omitted the code to set up the methods for that InternalPackedArray. This makes all the basic manipulation methods available.

bd219a7601 Add extras test for calling into runtime.
The alternative of passing an object template at context creation is
unfeasible because we need a context to instantiate the template.
At the time we create the context from snapshot or bootstrap from
scratch, we would already need that template instance, leading to a
chicken-and-egg problem.

This is an alternative that is simpler and less intrusive.

7f4fa3b8f1 Call builtin code wrapped in functions from the bootstrapper.
For the moment, we only pass the global object (the one we are setting up).
A few smaller changes were necessary to avoid failures in
test-object-observe/DontLeakContextOnObserve. Otherwise the global object
would be retained by being context allocated, leading to test failure.
