__WORDSIZE32_SIZE_ULONG should be defined to 0 but it's not defined at all for
many targets.

__WORDSIZE32_PTRDIFF_LONG is introduced for aarch64/ilp32, and also defined
for all other ports as well.

This patch is the part of aarch64/ilp32 work but it can be applied
separately as it fixes inconsistency in GLIBC.

	* sysdeps/aarch64/bits/wordsize.h : New file
	(__WORDSIZE32_SIZE_ULONG): Define.
	(__WORDSIZE32_PTRDIFF_LONG): New define.
	* sysdeps/mips/bits/wordsize.h: Likewise.
	* sysdeps/powerpc/powerpc32/bits/wordsize.h: Likewise.
	* sysdeps/powerpc/powerpc64/bits/wordsize.h: Likewise.
	* sysdeps/s390/s390-32/bits/wordsize.h: Likewise.
	* sysdeps/s390/s390-64/bits/wordsize.h: Likewise.

	* sysdeps/x86/bits/wordsize.h: Likewise.
	* sysdeps/generic/stdint.h: Use #if instead of #ifdef for that macros.
