Subject: 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.
