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.

Re-enabled for ASan (as the comment promised). - regress-crbug-160010: Throws "invalid string length" on all platforms. Was disabled everywhere. Dropped. - regress-crbug-514081: Test was previously changed to use 2MB instead of 2GB. Re-enabled variants. Additionally, it reorders a bunch of definitions: - Introduced separate sections for "mode == debug" and "no_i18n" to make the "ALWAYS" section cleaner. - Sorted various "slow tests", "open bugs", and "no_variants" definitions into groups. - Simplified long "arch == x or arch == y" sequences to "arch in (x, y)".

The regression test for crbug.com/976627 was: (1) silently failing on all platforms, (2) very brittle, baking in several internal limits, (3) highly specific for one particular place in the code, (4) when fixed, very slow: 6 seconds on x64.release. For all these reasons, it is herewith dropped.

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.

When comparing objects which get printed to very long strings (e.g. collections like vectors), it's much more readable if they get printed to individual lines. Differences are much easier to spot then. This CL refactors the CHECK/DCHECK macros to print the left hand side and right-hand side in individual lines if any of them is longer than 50 characters. To that end, the {PrintCheckOperand} method (only used from {MakeCheckOpString}) is changed to return the string directly instead of printing to an output stream.

This change moves the definitions of the bitfield flags used by Symbol and Map to Torque. Symbol could directly follow the pattern established by SharedFunctionInfo, but Map required some other changes: - Until now, Torque bitfield definitions have required unsigned types. I thought that this would be the least-surprising behavior, since we never sign-extend when decoding bitfield values. However, I believe that the amount of churn involved in making ElementsKind be unsigned outweighs the benefit we were getting from this restriction (and similar difficulties are likely to arise in converting other bitfield structs to Torque), so this CL updates Torque to allow signed bitfield values. - If we try to make Map extend from all of the generated classes that define its flags, we end up with class sizing problems because some compilers only apply empty base class optimization to the first in a row of empty base classes. We could work around this issue by generating macros instead of classes, but I took this as an opportunity for a minor clean-up instead: rather than having bitfield definitions for several different bitfield structs all jumbled together in Map, they can be split up. I think this makes the code a little easier to follow, but if others disagree I'm happy to implement macro generation instead.
