This adds a new struct "OOMDetails" which is passed to the OOMErrorCallback. It currently holds the "is_heap_oom" bool that was also passed before, plus an optional "detail" string. The struct can later be extended without having to change the signature of the OOMErrorCallback. Removing fields will have to follow the standard deprecation rules, but this is also easily possible without the hassle for this initial change. We modify the deprecated OOMErrorCallback definition and un-deprecate it, which can be seen as removing a deprecated API and adding a new one in one CL.

This fixes a flaky crash when running with --turbo-stats or --turbo-stats-wasm. With dynamic tiering, it can happen that a compilation job is started shortly before the program/test/benchmark terminates and the main thread goes through its teardown sequence. When such a late job finishes, it still wants to report its statistics, which currently crashes due to UAF if the CompilationStats object, which is owned by the main thread, has already been deleted.

Record old-to-shared references in the C++ write barrier. When an old-to-shared reference is created, this particular slot will be atomically inserted into the old-to-new remembered set. We already stopped clearing the old-to-new-remembered set after a shared GC, so we already need to be able to handle such slots when invalidating objects and in the sweeper.

SpaceWithLinearArea will holds a ref to a struct containing original_top_ and original_limit_ as well the lock used to sync them for querying IsPendingAllocation. PagedSpace is split into PagedSpaceBase (that holds all funcitonality) and PagedSpace. The actual fields are owned by PagedSpace and NewSpace. This is done in preparation for PagedNewSpace to allow PagedSpaceiBase and NewSpace to share the same original_top_ and original_limit_ fields.

We currently have a BitVector implementation which is used a lot by the two (mid-tier and top-tier) register allocators. Their size is the number of virtual registers or the number of blocks in the function. If one of those numbers gets huge, the BitVector does not perform well any more, and it consumes huge amounts of memory (we see up to several GBs for huge Wasm functions). This CL introduces a SparseBitVector implementation with a compatible interface, meant to replace the BitVector implementation. Usages will be introduced in follow-up CLs, first for the mid-tier allocator, then top-tier. This will allow us to assess performance changes better, and revert individual usages.
