Define wordsize.h macros everywhere
* bits/wordsize.h: Add documentation.
* sysdeps/aarch64/bits/wordsize.h : New file
* sysdeps/generic/stdint.h (PTRDIFF_MIN, PTRDIFF_MAX): Update
definitions.
(SIZE_MAX): Change ifdef to if in __WORDSIZE32_SIZE_ULONG check.
* sysdeps/gnu/bits/utmp.h (__WORDSIZE_TIME64_COMPAT32): Check
with #if instead of #ifdef.
* sysdeps/gnu/bits/utmpx.h (__WORDSIZE_TIME64_COMPAT32): Ditto.
* sysdeps/mips/bits/wordsize.h (__WORDSIZE32_SIZE_ULONG,
__WORDSIZE32_PTRDIFF_LONG, __WORDSIZE_TIME64_COMPAT32):
Add or change defines.
* 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.
