    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.
    >
