Make the three map's bitfields use release/acquire semantics. This ensures, for example, that when we set the number of own descriptors on the map we will do so with a release store. Also, start reading and writing said bitfields concurrently when concurrent inlining is enabled. Note the BIMODAL_ACCESSOR_WITH_FLAG_B macro which enables this.

Change SlotSet representation to a variable-sized array of pointers to buckets. The length of the array/number of buckets depends on the size of the page. Before this change the SlotSet always stored a fixed number of buckets. Large pages needed a SlotSet-Array to cover the whole object. Now both regular and large pages both use a single SlotSet object, which contains all bucket pointers.

This patch gives DescriptorArray its own visitor id and its own layout that is independent from the layout of WeakFixedArray. This allows us to use raw 16-bit integers for keeping track of the number of descriptors (total, non-slack, and marked). As a side-effect, we save one word per descriptor array on 64-bit. v8:8486 Change-Id: If8389dde446319e5b3491abc948b52539dba235c Reviewed-on: https://chromium-review.googlesource.com/c/1349245 Commit-Queue: Ulan Degenbaev <ulan@chromium.org> Reviewed-by: Igor Sheludko <ishell@chromium.org> Cr-Commit-Position: refs/heads/master@{#57845}

This replaces custom Release_CompareAndSwap implementation with a call to compiler intrinsic / std:atomic, which is TSAN friendly.
