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/i386/i686/cacheinfo.c
	(DISABLE_PREFERRED_MEMORY_INSTRUCTION): Removed.
	* sysdeps/i386/i686/multiarch/Makefile (aux): Remove init-arch.
	* sysdeps/i386/i686/multiarch/Versions: Removed.
	* sysdeps/i386/i686/multiarch/ifunc-defines.sym (KIND_OFFSET):

	* sysdeps/unix/sysv/linux/x86/Makefile
	(libpthread-sysdep_routines): Remove init-arch.
	* sysdeps/unix/sysv/linux/x86_64/dl-procinfo.c: Include
	<sysdeps/x86_64/dl-procinfo.c> instead of
	sysdeps/generic/dl-procinfo.c>.

	Add cpu-features-offsets.sym and rtld-global-offsets.sym.
	[$(subdir) == elf] (sysdep-dl-routines): Add dl-get-cpu-features.
	[$(subdir) == elf] (tests): Add tst-get-cpu-features.
	[$(subdir) == elf] (tests-static): Add
	tst-get-cpu-features-static.
