Original change's description:
> Add Windows ARM64 ABI support to V8
>
> This change added Windows ARM64 ABI support, major things are:
> 1. Excluding x18 register from any usage because it is reserved as
> platform register. Preserve alignment after the change.
> 2. Fix the assumption of LP64 in arm64 backend. Windows ARM64 is
> still LLP64.
> 3. Stack guard page probe for large allocation on stack.
>
> Reference:
> Windows ARM64 ABI:
> https://docs.microsoft.com/en-us/cpp/build/arm64-windows-abi-conventions?view=vs-2017
