Akim Demaille 09bc1b99c9 lalr1.cc: modern C++ no longer needs an assignment for symbols ...

Reported by Frank Heckenbach.

Actually the assignment operator should never be needed: the C++98
requirements for vector::push_back is CopyInsertable, which does not require
an assignment operator.  However, libstdc++ shipped with GCC up to (and
including) 6 uses the assignment operator (which affects Clang on top of
libstdc++, but also ICC).  So let's keep it for legacy C++.

See https://gcc.godbolt.org/z/q0XXmC.

* data/lalr1.cc (stack_symbol_type::operator=): Remove.
* data/c++.m4 (basic_symbol::operator=): Ditto.
* tests/c++.at (C++ Variant-based Symbols Unit Tests): Adjust.
