Fix LONG_WIDTH, ULONG_WIDTH include ordering issue.
As described in
<https://sourceware.org/ml/libc-alpha/2016-10/msg00047.html>, there is
an include ordering issue with the integer width macros in glibc's
<limits.h>, where definitions conditional on LONG_MAX do not work as
intended because when the headers are installed, this part of glibc's
<limits.h> is processed before the part of GCC's <limits.h> that will
define LONG_MAX. This patch changes the definitions just to use
__WORDSIZE for the expansion of LONG_WIDTH and ULONG_WIDTH rather than
making those definitions conditional on LONG_MAX.
Tested for x86_64 and x86.
* include/limits.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (LONG_WIDTH):
Define to __WORDSIZE, not conditional on [LONG_MAX ==
0x7fffffffL].
[__GLIBC_USE (IEC_60559_BFP_EXT)] (ULONG_WIDTH): Likewise.
