introduces the appropriate instance types for Map and Set

- Set.prototype.entries
- Set.prototype.values

Simplifies the implementation of IteratorClose in IteratorBuiltinsAssembler, and makes clear that it is only invoked when an exception occurs. Adds exception handling support to GetIterator, IteratorStep, and IteratorCloseOnException.
Moves the Promise.all resolveElement closure and it's caller to
builtins-promise-gen.cc.
Instead of creating an internal array (and copying its elements into a
result
array), a single JSArray is allocated, and appended with
BuildAppendJSArray(),
falling back to %CreateDataProperty(), and elements are updated in the
resolve
closure the same way. This should always be unobservable.

Port the baseline implementation of Object.prototype.isPrototypeOf to
the CodeStubAssembler, sharing the existing prototype chain lookup logic
with the instanceof / OrdinaryHasInstance implementation. Based on that,
do the same in TurboFan, introducing a new JSHasInPrototypeChain
operator, which encapsulates the central prototype chain walk logic.
This speeds up Object.prototype.isPrototypeOf by more than a factor of
four, so that the code
A.prototype.isPrototypeOf(a)
is now performance-wise on par with
a instanceof A
for the case where A is a regular constructor function and a is an
instance of A.
Since instanceof does more than just the fundamental prototype chain
lookup, it was discovered in Node core that O.p.isPrototypeOf would
be a more appropriate alternative for certain sanity checks, since
it's less vulnerable to monkey-patching. In addition, the Object
builtin would also avoid the performance-cliff associated with
instanceof (due to the Symbol.hasInstance hook), as for example hit
by https://github.com/nodejs/node/pull/13403#issuecomment-305915874.
The main blocker was the missing performance of isPrototypeOf, since
it was still a JS builtin backed by a runtime call.
This CL also adds more test coverage for the
Object.prototype.isPrototypeOf builtin, especially when called from
optimized code.

Properly propagate the fact that the function has a statically known name from
parser to SharedFunctionInfo objects. The empty string that has been set as
name before this CL does not help to distinguish cases like:
var o1 = { ''(){} };
var o1 = { [foo()](){} };
or
var o2 = { get ''(){} };

Different Intl features (DateTimeFormat, NumberFormat, etc) have
different lists of locales supported. Previously, the default locale
was set to "und", as opposed to what was detected from the surrounding
system, if any of these features was missing data. With this patch,
only that feature is set to "und". In this way, the data quality should
be just as good as if there were no fallback logic, but at the same time,
resolvedOptions().locale should show the locale actually in effect.

The spec requires that we use IterableToList, which we skipped for
some arrays as an optimization. We can't skip this for arrays with
objects though, because the objects may mutate the array during
the copying step via valueOf side effects.
Also clean up the implementation to use a runtime function rather
than a builtin as the helper. Also reverses the result of the helper
because I think it is a bit more intuitive that way.

The last CL https://chromium-review.googlesource.com/c/456707/ caused
some pretty heavy performance regressions. After experimenting, it
seems the easiest and most straight-forward way to copy the elements
into the new typed array is to do it in JS.
Adds a fast path for typed arrays, where the source typed array has
the same elements kind, in which case we can just copy the backing
store using memcpy.
This CL also removes regression test 319120 which is from a pwn2own
vulnerability. The old code path enforced a maximum byte_length
that was too low, which this change removes. The length property of
the typed array must be a Smi, but the byte_length, which can be up
to 8x larger than length for a Float64Array, can be a heap number.
We can also re-use some of the logic from ConstructByLength when
deciding whether to allocate the buffer on- or off-heap, so that
is factored out into InitializeBasedOnLength. We can also re-use
the DoInitialize helper instead of calling into the runtime,
meaning we can remove InitializeFromArrayLike.
