Remove the SWEEPING state from incremental marking. Sweeping is now always completed when starting incremental marking. Before this change there needed to be a safepoint each for starting marking and completing sweeping. Now both happens within a single safepoint.

Background threads can now start incremental marking when necessary. In contrast to the main thread they always need to schedule a job and can't start incremental marking right away. Background threads also use a simpler heuristic for deciding whether to start incremental marking.

This patch provides infrastructure to pin object types to specific spaces. This allows embedders to create mutual exclusive arenas for certain (base) types. In future, this will also be used to provide sliding-window compaction on certain custom spaces. We mainly preserve the existing infrastructure with the difference that spaces are now slightly more dynamic than in Blink as they are kept in a vector instead of a fixed-size array. The mechanism differs from Blink in that it does not allow the user object to call allocation methods directly but instead provides a trait that can be overridden to specify a custom space. The patch preserves templatization for objects that do not go into custom spaces to safe a branch in the allocation hot path.

When the memory reducer decides whether to do the next GC or not, it takes into account the number of detached contexts. This may lead to redundant GCs if the detached contexts are leaking and stay reachable. With the unified heap all unreachable detached contexts are freed in one GC, so this heuristic is no longer necessary.

This CL cleans up CompareOperationFeedback by replacing it with a composable set of flags. The interpreter is changed to collect more specific feedback for abstract equality, especially if oddballs are involved. TurboFan is changed to construct SpeculativeNumberEqual operator instead of the generic JSEqual in many more cases. This change has shown a local speedup of a factor of 3-10, because the specific operator is way faster than calling into the generic builtin, but it also enables additional optimizations, further improving runtime performance.
