The goal of the Int64Reducer is to replace all int64 nodes in a tf graph
with a set of int32 nodes such that 64 bit tf functions can be executed
on 32 bit platforms. At the moment the Int64Reducer only replaces
Int64Constants, TruncateInt64ToInt32, and Word64And.

The spec requires all Math functions to first call ToNumber on all
arguments before doing any other observable operation.  So early
return in case of Infinity is not valid.

Drive-by-fix: Remove the use of %_Arguments / %_ArgumentsLength and
use (strict) arguments instead of allocating a temporary InternalArray
explicitly.

So far, we've been moving down gaps wholesale. This change moves
individual move operations instead. This improves some benchmarks,
and should overall reduce code size, because it improves the chance of
reducing the number of moves.

For example, there are improvements on x64 in Emscripten (Bullet, in
particular) , JetStream geomean, Embenchen (zlib).

In the process of making this change, I noticed we can separate the
tasks performed by the move optimizer, as follows:

- group gaps into 1
- push gaps down, jumping instructions (these 2 were together before)
- merge blocks (and then push gaps down)
- finalize

We can do without a finalization list. This avoids duplicating storage -
we already have the list of instructions; it also simplifies the logic, since,
with this change, we may process an instruction's gap twice.

Compile time doesn't regress much (see pathological cases), but we
may want to avoid the allocations of the few sets used in the new code.
I'll do that in a subsequent change.

Revert of [api] Make ObjectTemplate::SetNativeDataProperty() work even if the ObjectTemplate does not have a … (patchset #3 id:80001 of https://codereview.chromium.org/1642223003/ )

Reason for revert:
Fails a lot of layout tests and blocks the roll. Can be easily reproduced with a local Chromium checkout.

Reference: https://codereview.chromium.org/1652413003/

Original issue's description:
> [api] Make ObjectTemplate::SetNativeDataProperty() work even if the ObjectTemplate does not have a constructor.
>
> Previously ObjectTemplate::New() logic relied on the fact that all the accessor properties are already installed in the initial map of the function object of the constructor FunctionTemplate.
> When the FunctionTemplate were instantiated the accessors of the instance templates from the whole inheritance chain were accumulated and added to the initial map.
> ObjectTemplate::SetSetAccessor() used to explicitly ensure that the ObjectTemplate has a constructor and therefore an initial map to add all accessors to.
>
> The new approach is to add all the accessors and data properties to the object exactly when the ObjectTemplate is instantiated. In order to keep it fast we now cache the object boilerplates in the Isolate::template_instantiations_cache (the former function_cache), so the object creation turns to be a deep copying of the boilerplate object.
>
> This CL also prohibits non-primitive properties in ObjectTemplate to avoid potential cross-context leaks.

This includes 2 fixes:
1) We didn't properly advance the holder when checking whether
Receiver==Holder, so we'd inadvertently block loading the property if
the first property we find is on the typed array.
2) Reflect.get may cause any object on the prototype chain of the holder
to be the receiver; so we need to recheck for this special state for
each object we perform lookup on.

Moves the temporary register allocator out of the bytecode array
builder into TemporaryRegisterAllocator class and adds unittests.
Particular must be taken around the translation window boundary
motivating the addition of tests.

Also adds a Clear() method to IdentityMap() which is called by
the destructor. This allows classes to hold an IdentityMap if
they are zone allocated. Classes must call Clear() before the zone
is re-cycled or face v8 heap corruption.
