[turbofan] Second round of optimisation for unordered comparisons on arm/arm64.
...
Avoid explicitly branching to the false label on unordered when the condition
on the true branch will not catch the unordered case and let the code fall
through.

When reading the map from a live object, use a barrier load
...
It could happen that we shrink a live object on the main thread (e.g.
MigrateFastToSlow) while we're sweeping the same page. The main
thread first creates a filler object that the release-stores the new
map. Therefore it's important to barrier load the map word of live
objects from the sweeper thread.

Optimize Object.seal and Object.preventExtensions
...
They both now run fast (due to utilizing transitions instead of always
creating new maps) and sealed or non-extensible objects can stay in
fast mode after transitioning.
This almost entirely reuses the code for transitioning objects
frozen by Object.freeze(), with the added benefit of freeing
up a bit on the map (we no longer keep track of frozen-ness,
as that bit wasn't used for anything interesting).
