Call and CallJSRuntime had a slightly different use of the register

to avoid memory leaks introduced by the message object. Also the message

This was inconsistent in the spec in case of has vs get, set. Removing
receiver==holder simplifies the lookup; so tentatively removing this
additional check which was broken until yesterday anyway. See

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.

We don't have proper test coverage for the no-deoptimization code paths

Revert of [regexp] implement /ui to mirror the implementation for /i. (patchset #2 id:20001 of https://codereview.chromium.org/1641613002/ )

Reason for revert:
This test fails:

assertEquals(["as"], /^a[\u017F]/ui.exec("as"));

The reason is that we end up with a character class that is not stand alone, so we do not perform case folding on it correctly (with unicode flag).
