fda19e0438 Add sysdeps/x86/dl-procinfo.c 
Add sysdeps/x86/dl-procinfo.c for x86 version of processor capability
information to reduce duplication between i386 and x86_64 dl-procinfo.c.

	* sysdeps/i386/dl-procinfo.c: Include
	<sysdeps/x86/dl-procinfo.c>.
	* sysdeps/x86_64/dl-procinfo.c: Likewise.

e2e4f56056 Add _dl_x86_cpu_features to rtld_global 
This patch adds _dl_x86_cpu_features to rtld_global in x86 ld.so
and initializes it early before __libc_start_main is called so that
cpu_features is always available when it is used and we can avoid
calling __init_cpu_features in IFUNC selectors.

	* sysdeps/i386/dl-machine.h: Include <cpu-features.c>.
	(dl_platform_init): Call init_cpu_features.
	* sysdeps/i386/dl-procinfo.c (_dl_x86_cpu_features): New.

	* sysdeps/unix/sysv/linux/x86_64/dl-procinfo.c: Include
