The number of arguments for the LiftoffCompiler has grown significantly since its initial implementation, and it becomes hard to keep track of all options at the call sites. This CL refactors all optional parameters into a {LiftoffOptions} struct which has a factory-like interface. This will allow us to add more options in the future, e.g. for dynamic tiering.

For inline scripts that have a `// #sourceURL=foo.js` annotation, the V8 inspector (and by extension `Error.stack`) currently operates in terms of the `foo.js`, i.e. doesn't give any hint about the actual source, except for the line/column offsets reported upon scriptParsed. However in case of stack frames (i.e. as part of `Error.stack` or as part of the call frames reported via CDP), the line/column offsets are relative to the actual source instead of relative to the `foo.js` part, which - besides other things - makes post-processing of recorded stack traces tricky (sometimes impossible). This change adjusts the source positions reported for (inline) scripts with sourceURL annotations to be relative to the (inline) script instead of the surrounding document.

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.
