glr2.cc: fix yycompressStack

Browse Source 
Currently, yycompressStack expects the free items to be states only.
That's not the case.

Fixes 712 and 730 pass.  748 still fails, but later and
differently (heap-use-after-free).

* data/skeletons/glr2.cc (glr_stack_item::setState): New.
(glr_stack_item::yycompressStack): Use it.
* tests/glr-regression.at: Adjust.
