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. * sysdeps/sparc/sparc32/bits/wordsize.h: Likewise. * sysdeps/sparc/sparc64/bits/wordsize.h: Likewise. * sysdeps/tile/tilegx/bits/wordsize.h: Likewise. * sysdeps/tile/tilepro/bits/wordsize.h: Likewise. * sysdeps/unix/sysv/linux/alpha/bits/wordsize.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/wordsize.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/wordsize.h: Likewise. * sysdeps/wordsize-32/bits/wordsize.h: Likewise. * sysdeps/wordsize-64/bits/wordsize.h: Likewise. * sysdeps/x86/bits/wordsize.h: Likewise.
