Blink uses Isolate::GetEnteredContext() to implement HTML's "entry
context" concept, and thus depends on it not being changed except
explicitly (by Blink.) To support this, stop entering contexts
implicitly in all external API entry points; rather just set the
context as current. The only thing that changes the entered context
is now Context::Enter()/Context::Exit() (and Context::Scope.)

1. Replaces --crankshaft with --opt in tests.
2. Also fixes presubmit to check for --opt flag when
assertOptimized is used.
3. Updates testrunner/local/variants.py and
v8_foozie.py to use --opt flag.
This would mean, nooptimize variant means there are
no optimizations. Not even with %OptimizeFunctionOnNextCall.

When a FunctionTemplate-based function is used as a constructor
and returns a JSProxy, we incorrectly treated that result the same
as a non-object result. Now it is treated like any other object
result, i.e., it becomes the result of the constructor call.

So that we can delete object properties without a runtime call.
The builtin implements a few fast paths (for now only deletion
of dictionary properties), and calls the runtime for all other
cases.

This new API sets a native data property on an object
directly, as Template::SetNativeDataProperty does.
It is similar to Object::SetAccessor, but properties
set by SetNativeDataProperty without kReadOnly flag
can be replaced.

The WebIDL spec expects iterator objects from interfaces that declare pair
iterators to ultimately inherit from %IteratorPrototype%. Expose the
intrinsic object in the public API so we can use it in Blink's bindings

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.

This CL renames all occurrences of "internal field" to "embedder field"
to prevent confusion. As it turns out, these fields are not internal to
V8, but are actually embedder provided fields that should not be mucked
with by the internal implementation of V8.
Note that WASM does use these fields, and it should not.

In addition to Array.prototype.values() which is already exposed, Blink
needs access to entries(), forEach() and keys() to properly set the
corresponding functions in value iterators for WebIDL conformance.
Add a few new entries to NATIVE_CONTEXT_IMPORTED_FIELDS and expand
V8_INTRINSICS_LIST, as well as some API tests for all these new exposed
functions.

Currently, to find out a Promise's status and result, one has to use the
debug context. This is for example done in Node.js. This new API is a
