[PATCH] [AArch64] Implement Clang CLI interface proposal about "-march".

[Eric Christopher]

One inline comment.

Also, I'm seeing tests for -mtune and -mcpu, but very few for -march= behavior. Can you make some of those similar to the -mcpu ones to make sure both ways work?

Thanks!

Same comment as last time. Split or Splitted. I'd prefer the first.
