lalr1.cc: fix exception safety

lalr1.cc does not reclaim its memory when ended by an exception.

Reported by Oleksii Taran:
http://lists.gnu.org/archive/html/help-bison/2012-09/msg00000.html

* data/lalr1.cc (yyparse): Protect the whole yyparse by a try-catch
block that cleans the stack and the lookahead.
