95b93c6e0d x86: Add sysdeps/x86/sysdep.h 
Add a new header file, sysdeps/x86/sysdep.h, for common assembly code
macros between i386 and x86-64.  Tested on i686 and x86-64.  There are
no differences in outputs of "readelf -a" and "objdump -dw" on all glibc
shared objects before and after the patch.

	* sysdeps/i386/sysdep.h: Include <sysdeps/x86/sysdep.h> instead
	of <sysdeps/generic/sysdep.h>.

c9070e6305 X86_64: Don't use PLT nor GOT in static archives [BZ #20750] 
There is no need to use PLT nor GOT in static archives to branch to a
function, regardless whether static archives is compiled with PIC or
not.  When static archives are used to create dynamic executable,
PLT/GOT may be used.  The resulting executable still works correctly.

	[BZ #20750]
	* sysdeps/x86_64/sysdep.h (JUMPTARGET): Check SHARED instead
	of PIC.

6901def689 Avoid an extra branch to PLT for -z now 
When --enable-bind-now is used to configure glibc build, we can avoid
an extra branch to the PLT entry by using indirect branch via the GOT
slot instead, which is similar to the first instructuon in the PLT
entry.  Changes in the shared library sizes in text sections:

Shared library    Before (bytes)   After (bytes)
libm.so             1060813          1060797
libmvec.so           160881           160805
libpthread.so         94992            94984
librt.so              25064            25048

	* config.h.in (BIND_NOW): New.
	* configure.ac (BIND_NOW): New.  Defined for --enable-bind-now.
	* configure: Regenerated.
	* sysdeps/x86_64/sysdep.h (JUMPTARGET)[BIND_NOW]: Defined to
	indirect branch via the GOT slot.

6fb8cbcb58 Improve 64bit memcpy/memmove for Atom, Core 2 and Core i7 
This patch includes optimized 64bit memcpy/memmove for Atom, Core 2 and
Core i7.  It improves memcpy by up to 3X on Atom, up to 4X on Core 2 and
up to 1X on Core i7.  It also improves memmove by up to 3X on Atom, up to
4X on Core 2 and up to 2X on Core i7.
