[PATCH] [ARM] Restructure cpu handling in the driver to mostly use the triple

[Renato Golin]

Hi John,

I'm about to commit some changes to ARMTargetParser that may affect your patch. I have tested both LLVM and Clang with it and found no bugs, but that doesn't guarantee much. I've also added a lot more unit tests to the Triple interface, which should stabilise things.

I was going to refactor this part later, but it seems that your changes are mostly orthogonal to what I planned. I'd welcome if you could rebase your changes after I send my patch, to make sure they still work as you'd expect.

cheers,
