[PATCH] Add cmov into i386 HWCAP_IMPORTANT

[GOTO Masanori]

Hi,

This patch adds HWCAP_I386_CMOV into i386 HWCAP_IMPORTANT.

CMOV is i686 optional instruction, and VIA C3 processor does not
support it, but VIA C3 reports it's an i686 class processor.  

Unfortunately, gcc generates this optional CMOV instruction with
-mcpu=i686 optimization, so i686 optimized dynamic library code almost
causes "illegal instruction" error on VIA C3 processor during dynamic
loading.  I heard that gcc team does not think to change using CMOV
instruction with i686 optimization.  CMOV is very key instruction to
make faster.

But I think this patch is needed regardless of gcc generates cmov
instruction code with i686 optimization.  Please apply it.

Regards,

	* sysdeps/unix/sysv/linux/i386/dl-procinfo.h: Add HWCAP_I386_CMOV
	into i386 HWCAP_IMPORTANT, because VIA C3 processor does not have
	i686 optional instruction CMOV.
