The UpdateSharedWasmMemoryObjects function only creates a new JSArrayBuffer when the the legths of old/new ArrayBuffer objects are unequal, but the CHECK in the Grow() funciton assumes that a new object is always created. Fix so that a new ArrayBuffer is always allocated.

Rather than explicitly requesting MAP_HUGETLB mappings, which requires kernel configuration, we should rely on the "Transparent Hugepages" feature, where eligible allocation requests are automatically fulfilled with huge page mappings.

To follow the style guide, and potentially improve performance, we switch to {int} for all stack offsets. The size of the stack cannot grow anywhere near {kMaxInt} anyway, and we have limits in place (for number of locals, number of parameters, and function body size) which also prevent this number from ever growing near that limit.

Note the tricky part in instruction-selector-x64, where we flip the inputs given to the code generator. This is because the semantics we want is: v128.andnot a b = a & !b, but the x64 instruction performs andnps a b = !a & b. Therefore we flip the inputs, and combined with g.DefineSameAsFirst, the output register will be the same as b, and we can use andnps without any modifications in both SSE and AVX cases.

For measuring the time spent in each phase of TurboFan we use PipelineRunScope that adds a RuntimeCallStats scope with the correct counter. PipelineRunScope uses the runtimestats table set on the PipelineData to initialize the RuntimeCallStats scope. We correctly set the runtimestats on the pipelineData when starting ExecuteJobs but don't set it on PrepareJobs. This cl fixes it to also set runtimestats table on PrepareJobs. PrepareJobs always run on main thread, so it should be safe to use the runtimestats table on the isolate.

Simulator-specific instructions are very useful, we can: - Place breakpoints that enable the simulator's interactive debugger, allowing us to see registers, the stack and print JS objects. - Enable and disable simulator tracing dynamically. - Call printf() directly, as the simulator cannot easily support its calling convention. However these tools are not available when generating builtins. The reason is that when cross-compiling, builtins are generated for real hardware but may still run inside the simulator on the host if we have a custom snapshot. Using the `v8_embed_script` GN option will do that for example but embedders may also do this with the V8 API. mksnapshot cannot tell the difference between generating code for a simulator build and a cross-build. If we change this, we can allow us to use simulator-specific features in builtins in simulator builds. So in this patch we: - Introduce a --target_is_simulator mksnapshot flag to drive the enable_simulator_code Assembler option. - Make sure the assembler respect the option instead of the USE_SIMULATOR macro.

When looking up a variable in a deserialized WITH scope, we were unconditionally passing in the cache scope to the lookup, even if the with was inside the cache scope. This would lead to and outer scope of the with holding the generated dynamic variable. If the cache scope was the SCRIPT scope, the dynamic variable would be interpreted as a global object property. Now, we only store the WITH scope dynamic variables in the cache scope if it is an inner scope of the WITH scope, same as we do for 'normal' scope lookups.

This makes the code a little more specific to what's happening: There is only 1 global scope, and if there is one, we know its declarations are info->scope()->declarations(). That means we don't need multiple GlobalDeclarationsBuilders, and we don't need to cache partially serialized versions of the declarations. One builder is enough, and we can simply walk those declarations if there are any. Additionally this CL drops unnecessary information passed into DeclareGlobals: - Global functions always have the name on the shared function info, so we can drop the name. - Due to lazy feedback vectors there's no point in trying to preinitialize global loads. Also this was only preinitializing global loads at the script level, not sub functions; without even checking whether the global load was used. It may actually have caused us to do more work and allocate more global load feedback slots than neccessary.

This CL adds the ArrayBufferExtension class, which is used to track JSArrayBuffers in a linked list. The ArrayBufferExtension is going to replace the ArrayBufferTracker in the future but is currently behind the v8_enable_array_buffer_extension feature flag. When enabled, each JSArrayBuffer has a corresponding native-heap allocated ArrayBufferExtension object. All extensions are currently tracked in a single linked list. During marking the GC not only marks the JSArrayBuffer but also its extension object. At the end of mark-compact the GC iterates all extensions and removes unmarked ones.

On most architectures, FP registers overlap with SIMD registers. A FP register holding a double can later be used to hold a 128-bit SIMD value. So, when pushing or popping used registers, we need to push the full width of the SIMD register. In ia32 and x64, we change the instruction from movsd to movdqu, and increment the offset by kSimd128Size. For arm64, we change the size of register when building the CPURegList. For arm, no change is needed, due to the way FP registers are paired up to form a single SIMD register (rather than overlap). Note for ports: PushRegisters and PopRegisters needs to be modified similarly for mips/mips64. ppc and s390 does not implement these methods, no change needed.
