We have a scratch available, so we can use it instead of asking for a temporary register from the register allocator. We can also relax the unique register requirement, since we are careful not to overwrite src0 or src1 in the codegen.

This field has been used with atomically relaxed semantics due to a race with layout_descriptor [1]. Even though layout_descriptor doens't exist anymore, this race is still present presumably because the transition to a new map happens on StoreIC. We can set it as atomic for non-cm and atomic relaxed for cm like we did with the other Map's fields. Note that originally, this field was relaxed so we are reverting it back to what it was for concurrent marking.

As per WebAssembly Web API[1], the engine should only consider names from the name section to synthesize function names in the context of call stacks. We previously also added support to harvest the exports table here in an attempt to improve the DevTools debugging experience, but that needs a separate fix specifically for the inspector (which should also take into account the imports to harvest names).

This change makes it possible to enable SharedArrayBuffer per Context, controlling whether it should be enabled or not with a callback. The previous implementation of the reverse origin trial for SharedArrayBuffer was broken, since the feature could only be enabled globally per process, and only if the feature flag is set early enough in the v8 initialization. This does not play well with how origin trials work. The implementation is similar to the callbacks that already exist for the origin trials for WebAssembly simd and exceptions. SharedArrayBuffer is still controlled by the flag harmony_sharedarraybuffer. If that flag is disabled, then SharedArrayBuffer is disabled unconditionally. On top of that, this CL introduces a new flag for enabling SharedArrayBuffer per context. If that flag is set, a callback is used to determine whether SharedArrayBuffer should be enabled. Note that this only controls whether the SharedArrayBuffer constructor should be exposed on the global object or not. It is always possible to construct a SharedArrayBuffer using new WebAssembly.Memory({ shared:true, initial:0, maximum:0 }).buffer.constructor; There are few things which I do not like of this approach, but I did not have better ideas: 1. The complex logic of dobule flag + callback. However, this seemed the best way to me to not break embedders which rely on that flag being enabled by default. 2. The fact that what actually matters is just whether the callback returns `true` once. It would be good to check that the callback gives a consistent return value, or to provide a better API that cannot be missunderstood.

We potentially emitted the same gap move multiple times to satisfy slot constraint of live ranges defined by a constant. Avoid this by keeping track of already spilled ranges for a given instruction. This is not expected to cause any regression because this case is rare. If it does, a better approach to save allocations would be to re-use the same vector by storing it somewhere that survives the function calls, e.g. in the ConstraintBuilder.

Simplifies the traversal of nodes in Scheduler::PrepareUses to avoid having to carefully order stack traversal for pre/post ordering visits. Instead simply pre visit when pushing a node onto the stack, then post visit the node when popping it from the stack and then visiting it's inputs. This keeps the same invariants required, but reduces visit overhead. In addition, move checking for CoupledControlEdges out of Increment/DecrementUnscheduledUseCounts such that the coupled control edge calculation only needs to be done once per node, rather than once for every input of the node. Also remove unecessary recursion from these functions. All told, these optimizations reduce the PrepareUses overhead by 40-50%.

Pointer cage reserved another register and inadvertently broke speculation poisoning by aliasing kSpeculationPoisonRegister with kInterpreterBytecodeArrayRegister (r12). This CL changes kInterpreterBytecodeArrayRegister to r11. Note that this changes it from being callee-save to caller-save, which required code reshuffling in a baseline builtin.

We don't have memory alignment yet, so using memory operands will cause segv if we try to access the unaligned operands (on non-AVX systems). The fix here is kept simple (the logic can be cleaned up a bit and optimized to not use unique registers), in order to keep the cherry-pick and back-merge as small and safe as possible.
