g++ implements the compiler side of this, I think.  GNU ld implements
the linker side.  It is called "section GC".  The idea is that you put
each function into its own section and then you simply don't link in
unused sections.

It might be complicated to implement this for gcj.  For instance you
have to deal with Class.forName in a reasonable way.  This is
important because some classes in libjava use forName.
