[PATCH] D49770: [ARM64] [Windows] Follow MS X86_64 C++ ABI when passing structs

ssijaric added a comment. Yes, it looks like the comment for the thumb case is applicable here as well. VC++ on ARM64 passes small structs with a destructor and a default copy constructor in a register, while clang passes them on the stack. I will probably address this in a separate patch.
