Optimize checking for identifiers.
* lib/m4sugar/m4sh.m4 (AS_IDENTIFIER_IF, _AS_IDENTIFIER_IF): New
macros, more efficient than regex on m4_re_word.
* lib/autoconf/general.m4 (AC_SUBST, AC_DEFINE_TRACE_LITERAL):
Rewrite in terms of new macro. As a side-effect, AC_DEFINE can
now use @&t@.
* configure: Regenerate.
