I've just committed these changes.  We've added a "mangled" attribute to
declarations.  It specifies the GCC-specific mangled version of a name.
This will not always match the name of the symbol as generated by the
compiler being simulated, but it will provide a valid identifier name that
uniquely corresponds to each declaration.
