[PATCH/c++] Handle constructors specially in linespec.c

[Daniel Jacobowitz]

If we're using GCC v3 and stabs, we don't get the names of constructors in
the ``struct type'' for the class.  I tried to fix this, but because of the
way the stabs reader works it's quite difficult.  Instead, for now, I'm
working around it in linespec.c.
