The mechanisms don't interact well. NodeObserver assumes synchronous compilation that finishes within the ObserverNodeScope. One could ensure all relevant lifetimes (of the NodeObserver itself, and all captured pointers) exceed that of all spawned jobs, but simply disabling the additional concurrent job in these cases is a pragmatic fix for now.

This reverts commit d16eefe0. It is not correct to check for node equality during the graph construction phase, because we can have optimizations that will combine same nodes. So it can happen that in wasm-compiler, the inputs to shuffle are not the same, so we canonicalize using that knowledge that it will not be the same, and allow indices > 15. But later we can have optimizations that combine the 2 inputs (e.g. splat of the same constants), and the instruction selector will see that the input nodes are the same.

Operands in Arm can be encoded as (8-bit value, 2*N bit left rotate). This encoding is checked for with the FitsShifter function. Previously, this encoding was exhaustively searched for by checking all 16 possible rotations. However, we can simply classify the different possible rotations as shifting away trailing zeros (without rotation), or rotating an 8-bit value split over the beginning and end of the 32-bit value (which, after one rotation, becomes the first case). Hence, we can replace the exhaustive search with a couple of trailing zeros calculations within these classes.

Add a new CRTP StaticCallInterfaceDescriptor class, which provides static constexpr getters for a descriptor's registers, parameter counts, and so on. Each CallInterfaceDescriptor subclass is changed to extend StaticCallInterfaceDescriptor, with StaticCallInterfaceDescriptor itself extending CallInterfaceDescriptor to still provide a dynamic lookup where needed. StaticCallInterfaceDescriptor provides a couple of customisation points, where it reads its CRTP derived descriptor's static fields and functions, with default fallbacks where appropriate. With these customisation points, the definition of CallInterfaceDescriptor subclasses is simplified to: a) Providing parameter names (as before) b) Providing parameter types (as before) c) Optionally setting flags (like kNoContext or kAllowVarArgs) as static booleans on the class. d) Optionally providing a `registers()` method that returns a std::array<Register, N> of registers that may be used for parameters (if not provided, this defaults to the implementation specific default register set). Parameter registers (and register count) are automagically set based on the number of parameters and number of given registers, with extra magic to ignore no_reg registers (to reduce ia32 special casing). The CallInterfaceDescriptorData is initialized based on these static functions, rather than manual per-descriptor initializers. This allows us to skip loading descriptors dynamically for CallBuiltin in Sparkplug, and instead lets us use a bit of template magic to statically set up arguments for the calls. Any other users of statically known descriptors will also benefit, thanks to C++ picking the static methods over the dynamic methods on the base class when available. Because we can remove various virtual functions and trigger heavier inlining of constantly known values, binary size slightly decreases with this change. Note that torque-generated descriptors are changed to use the same magic, rather than having Torque-specific magic, for consistency.

CanBeDeprecated looks at the DescriptorArray, and CanTransition at the instance_type. Both are safe to read concurrently and we just had to enable them with the macro.

- represent smis as fake heap numbers - numbers nodes (both smi and heap numbers) reference a child node whose name is "value" and whose entry is the string representation of that number That feature is disabled by default, and can be enabled by passing captureNumericValue: true when calling HeapProfiler.takeHeapSnapshot This patch slightly refactors some functions that operate on "essential objects". We now check that the object is essential before trying to create the entry. Otherwise, we would end up with smi objects created, but not referenced anywhere.

Port 06a2c2e0 Original Commit Message: We currently allow OSR (On-Stack Replacement) of arbitrarily deep return addresses. This is in direct violation of Intel CET's shadow stack, which we plan to enable eventually. This change works around this by postponing OSR until after we return to the old code. The main changes are: - Reserve a slot in Liftoff frames to store the OSR target, - Skip the return address modification, and instead store the new code pointer in the dedicated slot, - Upon returning to the old code, check the slot and do an indirect jump to the new code if needed. CET also prevents indirect jumps to arbitrary locations, so the last point is also a CET violation. Valid indirect jump targets must be marked with the ENDBRANCH instruction, which I will do in a follow-up CL.
