To display rhs symbols before a reduction, we used information about
the rule
reduced, which required the tables yyrhs and yyprhs. Now use rely
only on the
state stack to get the same information.
* data/lalr1.cc (b4_rhs_data, b4_rhs_state): New.
Use them.
(parser::yyrhs_, parser::yyprhs_): Remove.
I see no reason to keep these tables in all the skeletons (I have not checked whether GLR needs it though). I see no reason to keep bison generating their muscles either.
