H.J. Lu c22e4c2a14 x86: Extend CPUID support in struct cpu_features 
Extend CPUID support for all feature bits from CPUID.  Add a new macro,
CPU_FEATURE_USABLE, which can be used to check if a feature is usable at
run-time, instead of HAS_CPU_FEATURE and HAS_ARCH_FEATURE.

Add COMMON_CPUID_INDEX_D_ECX_1, COMMON_CPUID_INDEX_80000007 and
COMMON_CPUID_INDEX_80000008 to check CPU feature bits in them.

Tested on i686 and x86-64 as well as using build-many-glibcs.py with
x86 targets.

	* sysdeps/x86/cacheinfo.c (intel_check_word): Updated for
	cpu_features_basic.
	(__cache_sysconf): Likewise.
	(init_cacheinfo): Likewise.
	* sysdeps/x86/cpu-features.c (get_extended_indeces): Also
	populate COMMON_CPUID_INDEX_80000007 and
	COMMON_CPUID_INDEX_80000008.
	(get_common_indices): Also populate COMMON_CPUID_INDEX_D_ECX_1.
	Use CPU_FEATURES_CPU_P (cpu_features, XSAVEC) to check if
	XSAVEC is available.  Set the bit_arch_XXX_Usable bits.
	(init_cpu_features): Use _Static_assert on
	index_arch_Fast_Unaligned_Load.
	__get_cpuid_registers and __get_arch_feature.  Updated for
	cpu_features_basic.  Set stepping in cpu_features.
	* sysdeps/x86/cpu-features.h: (FEATURE_INDEX_1): Changed to enum.
	(FEATURE_INDEX_2): New.
	(FEATURE_INDEX_MAX): Changed to enum.
	(COMMON_CPUID_INDEX_D_ECX_1): New.
	(COMMON_CPUID_INDEX_80000007): Likewise.
	(COMMON_CPUID_INDEX_80000008): Likewise.
	(cpuid_registers): Likewise.
	(cpu_features_basic): Likewise.
	(CPU_FEATURE_USABLE): Likewise.
	(bit_arch_XXX_Usable): Likewise.
	(cpu_features): Use cpuid_registers and cpu_features_basic.
	(bit_arch_XXX): Reweritten.
	(bit_cpu_XXX): Likewise.
	(index_cpu_XXX): Likewise.
	(reg_XXX): Likewise.
	* sysdeps/x86/tst-get-cpu-features.c: Include <stdio.h> and
	<support/check.h>.
	(CHECK_CPU_FEATURE): New.
	(CHECK_CPU_FEATURE_USABLE): Likewise.
	(cpu_kinds): Likewise.
	(do_test): Print vendor, family, model and stepping.  Check
	HAS_CPU_FEATURE and CPU_FEATURE_USABLE.
	(TEST_FUNCTION): Removed.
	Include <support/test-driver.c> instead of
	"../../test-skeleton.c".
	* sysdeps/x86_64/multiarch/sched_cpucount.c (__sched_cpucount):
	Check POPCNT instead of POPCOUNT.
	* sysdeps/x86_64/multiarch/test-multiarch.c (do_test): Likewise.
