Add __CPU_MASK_TYPE for __cpu_mask
Since x86-64 and x32 use the same set of sched_XXX system call interface:

__cpu_mask should be unsigned long long, instead of unsigned long, for
x32.  This patch adds __CPU_MASK_TYPE so that each architecture can
define the proper type for __cpu_mask.

	[BZ #19313]
	* bits/typesizes.h (__CPU_MASK_TYPE): New.
	* sysdeps/mach/hurd/bits/typesizes.h (__CPU_MASK_TYPE): Likewise.
	* sysdeps/nacl/bits/typesizes.h (__CPU_MASK_TYPE): Likewise.
	* sysdeps/unix/sysv/linux/alpha/bits/typesizes.h (__CPU_MASK_TYPE):
	Likewise.
	* sysdeps/unix/sysv/linux/generic/bits/typesizes.h (__CPU_MASK_TYPE):
	Likewise.
	* sysdeps/unix/sysv/linux/s390/bits/typesizes.h (__CPU_MASK_TYPE):
	Likewise.
	* sysdeps/unix/sysv/linux/sparc/bits/typesizes.h (__CPU_MASK_TYPE):
	Likewise.
	* sysdeps/unix/sysv/linux/x86/bits/typesizes.h (__CPU_MASK_TYPE):
	* sysdeps/unix/sysv/linux/bits/sched.h (__cpu_mask): Replace
	unsigned long int with __CPU_MASK_TYPE.
