[PATCH] D103184: [AArch64] handle -Wa,-march=

[David Spickett via Phabricator via cfe-commits]

> I understand it's a little bit confusing here, but I was simply trying to match GCC's behavior (please see the example in my last comment) unless I misunderstood its output. I definitely agree having consistent behaviors between Arm and Aarch64 in Clang is more reasonable (in fact that was what I implemented at first) and maybe we should fork from gcc, WDYT?

If gas handles `march` by choosing the last value, then we don't need to emit multiple values just to look more like GCC's processed arguments.

Let me check what gas does when you run it directly, I think that's the best way to guide things.
