c++: report the stack at the same places as in C

Browse Source 
Let's have C be the reference, and match it elsewhere.  Maybe C is too
verbose and some adjustments are needed, but then that would be done
in another batch of patches.

* data/skeletons/lalr1.cc: Print the stack once we popped after
YYERROR, and before emptying the stack at the end of parsing.
