Some ValueKinds were defined based on the size of a system pointer or the size of a tagged value. In order to be able to reuse those definitions in both LiftoffAssembler and LiftoffCompiler, define them as public constants on LiftoffAssembler. Also, avoid the "ValueType" suffix, since they are not ValueTypes, but ValueKinds.

In contrast to wasm modules, asm.js modules have an empty source URL. Thus loosen a DCHECK and handle the nullptr source_url correctly. Also add regression tests that check that we don't crash. Those can later be extended to check that the profile looks as expected; for now they only check that we terminate.

It could happen that a background thread expands the heap by one page, but by the time the thread tries to allocate on it the space is already used by other background threads. If this happens three times in a row, V8 would crash with an OOM error. This CL prevents such situations by always allocating the object immediately at area_start().

The generated Torque files class-verifiers.cc and class-debug-readers.cc currently include files which are part of v8_initializers, despite being used in unrelated build targets. This change removes the unnecessary inclusions. There is still a lot of code included via all-objects-inl.h, but that's because these files require full class definitions for every object type.

This ensures that after the function-entry stack check, the instance will still be available in a register. The cost is having to reload it from the stack in the OOL code for the stack check, even though it is not clear if that register will still be used. This does not affect code size significantly (~0.25% reduction), but can improve performance a little bit if there are memory accesses or other instructions that require the instance right at the beginning of the function.

With the value stack refactoring in 1b5c7e15 / r73193, the combination of helper functions called by PeekArgs() ended up checking the stack height repeatedly. This CL avoids that by introducing a ValidateArgType() helper that does not check stack height. Bonus: achieve a small speedup by special-casing two of the most common opcodes in the decoder's main dispatcher.

When objects are recorded for conservative handling and the GC is finalized conservatively, with a different stack, we rely on MarkNotFullyConstructedObjects(). In this method, the objects are initially marked, only to be forwarded to handlers that try to mark them again.

This change relands the last part of https://crrev.com/c/2601880 . ScopeInfo has a vestigial 'length' field from when it used to be a FixedArray. This change removes that field, which saves some memory. More specifically: - Make ScopeInfo inherit from HeapObject, not FixedArrayBase which supplied the 'length' field. - Change FactoryBase::NewScopeInfo to allocate the updated object shape. It maintains the existing behavior of filling the newly-allocated object with undefined, even though that's not a valid ScopeInfo and further initialization is required. - Change a few length computations to use HeapObject::kHeaderSize rather than FixedArray::kHeaderSize. - Remove an unnecessary heap verifier function.

Resize() may be used to adjust additional trailing bytes of an object. It is up to the embedder to ensure correctness in case of shrinking.
