Given that there is no real controversy to make strcmp the same in
x86-64 libc and ld.so, I am checking in this patch.  I will post a separate
patch to make strcmp_sse2_unaligned as default.

Subject: [PATCH] Use SSE2 optimized strcmp in x86-64 ld.so

Since ld.so preserves vector registers now, we can use the same SSE2
optimized strcmp in x86-64 libc and ld.so.

	* sysdeps/x86_64/strcmp.S: Remove "#if !IS_IN (libc)".
