crrev.com/c/3069146 fixed a write barrier issue leading to a null dereference on Windows that was triggered by having the stack allocated at address below 4GB.

For some reason, the "ret" instruction goes missing on Mac release builds, probably because the compiler decides to split the inline assembly block and move the "v8_probe_memory_continuation" block somewhere else. This CL fixes that by adding another explicit "ret" at the end of "ProbeMemory". Also, we remove the "v8_probe_memory_address" symbol (which is identical to just "ProbeMemory"), to prevent the compiler from splitting "ProbeMemory" and "v8_probe_memory_address".

Maximum frame size (in bytes) is used to check for stack overflows in the prologue. The maximum number of call arguments is pre-calculated and included in this check. However the count was added to the frame size wihout converting the count to bytes, resulting in inaccurate stack overflow checks.

In crrev.com/c/3056970 I merged reporting allocated bytes from CppHeap to v8 with reporting from cppgc to CppHeap. The reporting handler assumed in_no_gc_scope() is false. Unfortunately this breaks. On heap termination, cppgc will report to CppHeap but CppHeap will have entered a no gc scope when it detached from the isolate. We could adjust the DCHECK, but I think it's simpler to revert to the previous unmerged state and simply port the bug fix from crrev.com/c/3056970 (i.e. lines 484-486 in cpp-heap.cc in this CL).

The field is immutable after initialization and thus should be set non-atomically on the main thread, and read non-atomically on the background thread. But TSAN support for generated code turns all field accesses into relaxed atomic accesses, leading to this race detection. Silence it by making the read relaxed as well.

Windows can allocate the stack at low addresses. A low-address on-stack slot (e.g. backing store reference for Blink's on-heap collections) with a null value would make TryGetCagedHeap falsely think that the slot resides in a caged heap that starts at a null address. We will still crash for low-address on-stack slots with non-null on-stack value, since these cases are not considered valid and should not happen. The null value check is added only to Windows. It is not an issue on other OSes where the stack always resides at high addresses and we prefer to keep the write barrier as cheap as possible.

While reading through the jump threading implementation, I noticed something strange: ApplyForwarding iterates through the block list in reverse post-order, not in assembly order. Thus, the value prev_fallthru might not refer to the previous block in assembly order. Obviously it works fine this way or we would have noticed by now, but I think that this step would be a little easier to read and reason about if the iteration used assembly order instead. I've added a test case to demonstrate the difference when using assembly order: in a diamond where the right side starts with an empty deferred block, the current implementation would fail to replace that block with a nop. I doubt this case would have any real-world impact.

Windows.h causes massive namespace pollution with its defining of many macros, it adds to build times, it disables warnings, and it makes it easier to write non-portable code. This change removes windows.h from V8's win32-headers.h. It does this by replicating the small number of typedefs that are needed and by defining three "proxy" types that are the same size and layout. The V8ToWindowsType functions are used to reinterpret_cast between the types. Prior to this change there were over 760 v8-related source files that include windows.h. After this change there are 16.

This ports https://crrev.com/c/3040844 to also work on Mac. All that's needed is minor tweaks to the inline assembly. The inline assembly is stripped down to what's actually needed. I didn't find documentation on ".pushsection" and ".popsection" on Mac. Since we do not have this on other inline assembly (e.g. src/heap/base/asm/x64/push_registers_asm.cc) removing this here does not regress the status quo. If this ever causes problems, we will have to consistently add it everywhere. The new code paths are tested by the v8_mac_arm64* CQ bots, and the "V8 Mac - arm64 - sim - {debug,release}" waterfall bots.

Previously the V8 inspector would only turn embedder accessors on the prototype chain into data properties, but would not do the same for ECMAScript builtins, which is kind of inconsistent and weird behavior. This leaves in the hack that the inspector reports native accessor properties as (own) data properties, but now at least the very least does so consistently. In the absence of a better solution, we'll go with this for now.
