CodeAssembler::Parameter now takes a Type template parameter and performs a checked cast to it. There is also UncheckedParameter which returns a TNode but doesn't check the cast. The original Parameter method is still there as UntypedParameter. Parameter<T>(x) in many cases replaces CAST(Parameter(x)), where the cast is performed inside Parameter. Since Parameter is not a macro, this means it cannot see the original expression or its file name and line number. So the error messages are vaguely useful, Parameter<T>() takes a SourceLocation parameter which with a default value of SourceLocation::Current(), which at least gives us the file name and line number for the error message.

This change moves external pointers into a separate table and turns external pointers in heap objects into indices into that table. This CL implements one of two possible ownership models for the table entries. With this one, every heap object owns its table entries, and they are allocated when the owning object is allocated. As such, setting external pointer fields does not require allocation of table entries. On the other hand, table indices cannot be shared between multiple objects. This CL does not yet implement freeing of external pointer table entires. This will later happen by a table garbage collector.

Previously, our Torque definition of JSArrayBuffer included only the first two fields. This allowed access to those two fields, but was somewhat confusing and obviously didn't let Torque code access the other fields. This change: - Completes the JSArrayBuffer layout definition; - Moves the associated bitfield struct definition to Torque; - Moves a couple of JSArrayBuffer macros to Torque; - Adds a reducer case so that the code generated using these new macros is not worse than what was generated previously.

There is a copy of the pointer decompression logic in TypedArrayBuiltinsAssembler::SetJSTypedArrayOnHeapDataPtr, which was not updated for the new ("smi-corrupting") pointer compression scheme: it erroneously used a sign-extending cast from compressed to full representation. This causes incorrect values to be computed when the heap size can grow beyond 2GB.

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.

Forbid using LoadRoot in CSA (with a bailout via CodeAssembler), so that users are forced to use helper macros for roots, which have statically known types. Convert all current uses of LoadRoot to use these macros, introducing new ones where necessary.

Replace uses of WordEqual on two tagged representation nodes with a new TaggedEqual helper, which on pointer compressed configs only compares the bottom 32-bits of the word. We no longer allow using WordEqual on anything not known to be a WordT (i.e. Node* or TNode<Object>). In the future, this may allow us to ignore the top bits of an uncompressed Smi, and have simpler decompression, though this patch is not sufficient for such a change. As a necessary drive-by, TNodify a bunch of stuff.

This disallows using CSA macros from Torque that have a Node* return type instead of TNode<>. By enforcing CSA types at the boundary between CSA and Torque, we can ensure that the Torque types and the CSA types match. As a drive-by, this CL adds a bit more of CSA typing where it made sense.

Extract the maximum on-heap typed array size to a constant in the JSTypedArray class. Add tests for allocating typed arrays of various sizes and validate through the API whether they are allocated on heap. It is not possible to observe from JavaScript.

This change adjusts object initialization order for a few classes so that the GC can never see those objects in an invalid, partially- initialized state. AccessorInfo: Just zeros out a few fields upon construction. This is the simplest case. FunctionTemplateInfo: Slightly changes the order in which fields are set, so that the Smi field is set ahead of the call to SetCallHandler, which can GC. Also a pretty simple case. JSListFormat, JSPluralRules, JSRelativeTimeFormat, JSSegmenter: The spec requires that we start with OrdinaryCreateFromConstructor, which has observable side effects (it fetches the prototype from the new.target). So we split JSObject::New in half: the first half does all of the user- visible things and returns a Map, which we can pass to the second half when we're ready to actually allocate the object. JSTypedArray: Extends the pattern from JSListFormat into Torque code: start with a Map and don't allocate the object until we're ready to set all of its properties.

Instead of generating one CodeStubAssembler-like class per namespace, Torque-generated macros are now free-standing functions not included from CSA code, and explicitly exported macros become part of the new TorqueGeneratedExportedMacrosAssembler, which CodeStubAssembler inherits from, thus making them available to all CSA code. Structs are now defined in a new header csa-types-tq.h as free-standing types with the prefix "TorqueStruct". This is a preparation for generating per Torque-file instead of per namespace.
