ghc and aarch64?

Hi David,

AArch64 is completely new architecture so it's not about extending 
current ARM support but rather write a new beside it -- at least as a 
prototype, if there is a lot of synergies you can merge both together 
later, but I don't see it having a high chance. Well the situation with 
AArch64 and ARM is very similar to situation with i386 and amd64 support 
so you can get an idea what's the difference (extended registers set, 
extended registers width, extended NEON (the least important detail 
indeed), different calling convention, etc.)
