Eliminating the extra list wrapping applied to regular

expression objects in the syntax tree. The parser
just puts out a #<regex ...> instead of (#<regex ...> regex-syntax).

* eval.c (do_eval): We no longer need the hack of
treating (#<regex> ...) as a special form which
evaluates to #<regex>.
(expand): We no longer have to skip over regex syntax,
so the case is removed.

* match.c (h_var, do_txeval, do_match_line): regexp cases are no longer
subcases of consp but stand on their own. In do_match_line, we
introduce a COBJ case into the type switch for regexes.

* parser.y: regexes are now compiled in the regex and lisp_regex
grammar rules instead of the dependent rules, and are not wrapped in
extra syntax.

 	* match.c (h_var): Fix regression introduced in 2014-08-11
 	commit. The incompleteness of that change broke the case of an unbound
 	variable followed by a bound variable. The value of the
