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):
Removed.
* sysdeps/i386/ldsodefs.h: Include <cpu-features.h>.
* 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>.
* sysdeps/x86/Makefile [$(subdir) == csu] (gen-as-const-headers):
Add cpu-features-offsets.sym and rtld-global-offsets.sym.
[$(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.
* sysdeps/x86/Versions: New file.

* sysdeps/x86_64/cacheinfo.c (__cpuid_count): Removed.
Assume USE_MULTIARCH is defined and don't check it.
(is_intel): Replace __cpu_features with GLRO(dl_x86_cpu_features).
