deopt-unlinked.js: bytecode flushing destroys the information that
%GetDeoptCount relies on, so turn that off for this test.
cleanupsome-after-unregister.js: the function-local object {o} is
assumed to be alive throughout the function, so make sure its live
range (from the optimizing compiler's view) extends that far.
Drive-by cleanup: drop some unnecessary casting boilerplate from
Genesis::InitializeGlobal_harmony_intl_date_format_range().

MicrotaskQueue associated to Context may be null after DetachGlobal,
and triggering FinalizationGroup clean up on the detached context
causes a crash.
This CL fixes the crash by cancelling the clean up on such a context.

New API is here: https://github.com/tc39/proposal-weakrefs/issues/55
The WeakCell parts stay in the old API, resulting in temporary code duplication
in some parts. Those parts will go away once the WeakCell-related parts are
migrated to the new API (but the spec needs some work first).

This replaces Runtime_RunMicrotasks with Runtime_PerformMicrotaskCheckpoint.
RunMicrotasks forcibly runs Microtasks even when the microtasks are suppressed,
and may causes nested Microtasks in a problematic way. E.g. that confuses
v8::MicrotasksScope::IsRunningMicrotasks() and GetEnteredOrMicrotaskContext().
OTOH, PerformMicrotaskCheckpoint() doesn't run cause the failure as it
respects the microtask suppressions.
As all existing tests don't call RunMicrotasks() in the suppressed situation
(like Promise.resolve().then(()=>{%RunMicrotasks();})), this change should
not affect to these tests.

- Add the WeakRef class and its deref() function.
- Add WeakFactory.prototype.makeRef
- Implement the "keep during job" behavior for WeakRef constructor and deref().
- Here we keep the targets alive longer than until the end of the job
(microtask), contradicting the spec. However, this is probably the indended
behavior, see https://github.com/tc39/proposal-weakrefs/issues/39 .

These tests rely on dropping references to objects either explicitly ("o =
null;") or implicitly ("o goes out of scope") and then doing gc. It's essential
that we haven't already marked the WeakCell pointing to o and marked it alive
before dropping the reference.

- Store dirty JSWeakFactories in a heap root (not native context) -
during GC there's no native context necessarily.
- Schedule one microtask per JSWeakFactory.
- Enter the context of the cleanup function before calling it.

If the user's cleanup function didn't iterate all available WeakCells, we need
to schedule the cleanup task again at some point. The previous condition
resulted it never being scheduled.
