Make strcmp with unaligned load/store the default hjl/unaligned
Since strcmp_sse2_unaligned performs better on current Intel and AMD
processors, this patch makes it the default.

	* sysdeps/x86_64/strcmp.S: Moved to ...
	* sysdeps/x86_64/multiarch/strcmp-sse2.S:  Here.  Remove
	"#if !IS_IN (libc)".  Remove libc_hidden_builtin_def (STRCMP).
	(STRCMP): Defined to __strcmp_sse2 if not defined.
	* sysdeps/x86_64/multiarch/strcmp-sse2-unaligned.S: Moved to ...
	* sysdeps/x86_64/strcmp.S: Here.  Remove "#if IS_IN (libc)".
	Add .text.  Add libc_hidden_builtin_def (strcmp).
	(__strcmp_sse2_unaligned): Renamed to ...
	(strcmp): This.
	* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
	strcmp-sse2.
	* sysdeps/x86_64/multiarch/strcasecmp_l-ssse3.S: Include
	strcmp-sse2.S instead of ../strcmp.S.

	[USE_AS_STRCMP] (STRCMP): Load __strcmp_sse2 instead of
	STRCMP_SSE2.
	[USE_AS_STRCMP] (strcmp): Defined __strcmp_sse2_unaligned if
	in libc.
	[!USE_AS_STRCMP]: Include strcmp-sse2S instead of ../strcmp.S.
	* sysdeps/x86_64/strcasecmp_l.S: Include multiarch/strcmp-sse2.S
