When accessing a super property which is a getter, the receiver
is not restricted the same way as when doing normal property access.

In particular, the receiver can be null / undefined.

Original change's description:
> [heap] Introduce LocalIsolate for main thread
>
> Add a LocalIsolate for the main thread to Isolate. This LocalIsolate is
> kept alive during the whole lifetime of the Isolate. The main thread
> LocalIsolate starts in the Running state in contrast to the background
> thread LocalIsolates (those start in Parked).
>
> Code paths in Turbofan that used to create a LocalIsolate on the main
> thread can now simply use the main thread LocalIsolate.
>
> LocalIsolate for the main thread will help in reducing differences
> between the main and background threads. The goal is that the main
> thread behaves more like a background thread.
>
> The main thread LocalIsolate should also make it simpler to share code
> between main thread and background threads by using LocalIsolate for
> both.

Megamorphic load builtins are a performance optimization when current

There is a flag in the WebAssembly trap handler that is set whenever
WebAssembly code is entered, and that is reset when WebAssembly code is
left. In runtime functions we have DCHECKs in place that check the
value of this flag.

This flag is only needed when trap handlers are enabled though. When
trap handlers are disabled, the flag is not enabled and disabled
consistently. DCHECKs should therefore only check the flag value when
trap handlers are actually enabled.

AssembleCode used CcTest::i_isolate() to load the isolate, however this
might not be the isolate that should be used. Therefore take the isolate
as an explicit argument.

Note that this changes behavior of ExecuteMemoryAccess in
test-sync-primitives-arm.cc. I think this test inadvertently created
the assembly code in the isolate of another thread, while it didn't
use the isolate it sets the handle scope up for.

This CL fixes a spot (pointed out by Mythri) in which it was possible
to start running unoptimized bytecode even if cached NCI code was
present.

Previously, the CompileLazy builtin would skip the runtime and start
running bytecode immediately if the SharedFunctionInfo was already
compiled; any NCI code was ignored.

This CL changes the CompileLazy builtin to additionally check the
SFI::may_have_cached_code bit. If set, call into the (new) function
Runtime::kTryInstallNCICode to try and install NCI code.

In https://crrev.com/c/v8/v8/+/2536465 we added acquiring the lock in
WriteToFlat. Then, acquiring in TryStringToDouble not only is not
necessary but also has undefined behaviour.

This was causing timeouts and meant the tests were disabled in
https://crrev.com/c/v8/v8/+/2543398.
