H.J. Lu 0b5395f052 Update x86_64 multiarch functions for <cpu-features.h> 
This patch updates x86_64 multiarch functions to use the newly defined
HAS_CPU_FEATURE, HAS_ARCH_FEATURE and LOAD_RTLD_GLOBAL_RO_RDX from
<cpu-features.h>.

H.J. Lu 6f6f1215f6 Support multiarch for i686. 
This patch adds multiarch support when configured for i686.  I modified
some x86-64 functions to support 32bit. I will contribute 32bit SSE string
and memory functions later.

Ulrich Drepper 8ea2372936 Fix up sched_cpucount in x86-64. 
Now that static executables can handle IFUNC functions don't exclude
optimization for sched_cpucount for !SHARED.

Ulrich Drepper 963cb6fcb4 Simplify CPUID value handling. 
SO far Intel and AMD use exactly the same bits meaning the same
things in CPUID index 1.  Simplify the code.  Should an architecture
come along which doesn't use the same semantics then it must use a
different index value than COMMON_CPUID_INDEX_1.
