FYI: lalr1.cc: Remove root

[Akim Demaille]

Index: ChangeLog
from  Akim Demaille  <address@hidden>

        Remove b4_root related material: failure experiment
        (which goal was to allow to derive from an class).

        * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
        definitions and uses.
