Note the _InterlockedCompareExchange128 for a x86_64 machine is only
defined as intrinsic when -mcx16 option is enabled.
But we use always use the intrinsic definition on x86_64 so that
compilation done without the -mcx16 could be detected (on C++ only).
And the intrinsic has been added recently to aarch64 machine for clang.
