Optimize m4_for.
* lib/m4sugar/m4sugar.m4 (m4_for): Use fewer macros.
(_m4_for): Take additional parameter, for fewer m4_indir calls.
* lib/m4sugar/foreach.m4 (_m4_foreach, _m4_shiftn, m4_do)
(m4_reverse, _m4_list_pad, _m4_list_cmp): Adjust all callers.
* doc/autoconf.texi (Looping constructs) <m4_for>: Document subtle
semantic change caused by the optimization.
* tests/m4sugar.at (M4 loops): Test the new semantics.
