[PATCH] D80163: [X86][VARARG] Avoid spilling xmm registers for va_start.

> Do we need better i686- triple testing?

It looks like I misunderstood the question. This patch should affect X86-64(AMD64 abi) only and should not affect 32-bit abi.  Thus I would add checking for i386,i686 triples into the llvm/test/CodeGen/X86/x32-va_start.ll. That test would show that 32-bit abi is not affected(as it currently is checked for -mtriple=x86_64-linux-gnux32 -mattr=-sse).
