Optimize three-valued comparison between integers. (a > b ? 1 : a < b ? -1 : 0) is the same as (a > b) - (a < b). * m4/gnulib-common.m4 (gl_COMMON): Define _GL_CMP. * lib/c-strcasecmp.c (c_strcasecmp): Use _GL_CMP. * lib/c-strncasecmp.c (c_strncasecmp): Likewise. * lib/dfa.c (compare): Likewise. * lib/fts.c (fts_compare_ino): Likewise. * lib/mbmemcasecmp.c (mbmemcasecmp): Likewise. * lib/mbscasecmp.c (mbscasecmp): Likewise. * lib/mbsncasecmp.c (mbsncasecmp): Likewise. * lib/memcasecmp.c (memcasecmp): Likewise. * lib/memcmp2.c (memcmp2): Likewise. * lib/savedir.c (direntry_cmp_inode): Likewise. * lib/strcasecmp.c (strcasecmp): Likewise. * lib/strncasecmp.c (strncasecmp): Likewise. * lib/unistr/u-cmp2.h (FUNC): Likewise.
