In the specific case of i386 to x86_64, you get better performance for
64 bit in many more cases because of the larger register set in x86_64.
This isn't the case with some other architectures (e.g. SPARC or PPC),
but is why 64 bit on Intel/AMD architectures is almost always a "win"
compared to 32 bit on the same CPU.
