Add 64-bit MS _Interlocked functions as builtins again

Add 64-bit MS _Interlocked functions as builtins again

Summary: Previously global 64-bit versions of _Interlocked functions broke buildbots on i386, so now I'm adding them as builtins for x86-64 and ARM only (should they be also on AArch64? I had problems with testing it for AArch64, so I left it)
