Now a descriptor array tracks the number of descriptors that were already marked. The marking visitor of a map only marks the subset of the descriptors that it needs and that are not already marked. If a descriptor array is shared between M maps and has N descriptos, then the number of marking operations is reduced from O(M*N) to O(N). This patch also adds a marking barrier for descriptors. The marked descriptor counter in a descriptor array is not cleared after mark-compact GC. Instead, it embeds two bits from the global mark-compact epoch counter and is considered 0 if the bits do not match the current value of the global epoch counter.

This CL improves load times by up to 6x. This is achieved by not setting event handlers per-line, but setting one event handler on the container. Unfortunately, load times are dominated by the graph view, which needs to be addressed in another CL.

Reachability is already being tracked in the function body decoder. This CL adds a DCHECK that the reachability tracked in the SsaEnv matches the reachability tracked in the function body decoder. Most of our methods will only be called for reachable code anyway. For exceptions, we still track reachability explicitly for now in the wasm graph builder, this can be refactored in the future by improving reachability tracking for catch blocks in the function body decoder. If this DCHECK survives fuzzing for a few days, we can remove code that handles unreachable code in graph-building-interface.cc.

We don't eagerly throw for assignments to calls; see v8:4480. They are simply turned into assignments to Property instead. We need to record a declaration error, however. Otherwise we'll end up with a Property in a declaration context. To reduce the scope of the lazy throwing, in this fix I record a pattern error instead, making calls as assignment target in a destructuring assignment context throw eagerly.

This CL moves variables that control MicrotaskQueue to MtQ itself. Namely, * is_running_microtasks_ and microtask_completed_callbacks_ from v8::internal::Isolate * microtasks_depth_, microtasks_suppressions_ and debug_microtask_depth_ from v8::internal::HandleScopeImplementer. As the current implementation has these variables one per-Isolate rather than per-MicrotaskQueue, this is needed to have multiple MicrotaskQueues for an Isolate.

This CL extracts the processing of imported globals into a separate function. Aside from copying the code, I made the following changes: * Rename {index} to {import_index}. This CL does minimal changes to the processing of globals itself. That code looks quite complex at the moment.

On MIPS and MIPS64, UseScratchRegisterScope has only one register for the scratch register [1,2], and TurboAssembler::CallCFunctionHelper runs out of it as fast_c_call_caller_fp_address uses the register.
