Port UnixPkg to also support X64. Currently only supports Unix x86_64 ABI. In the future we can make Sec support x86_64 ABI and the rest of the code support X64 EFI ABI. This will require assembly gaskets to fix the calling convention differences. I currently have noop gaskets in place for x86_64 ABI. This has only been tested on OS X 10.6.
